In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().
This issue was detected by using the Coccinelle software.

The patch 10209abe87f5ebfd482a00323f5236d6094d0865
usb: dwc2: gadget: Add scatter-gather mode
avoided a NULL pointer dereference (hs_ep->req == NULL) by
calling dwc2_gadget_fill_nonisoc_xfer_dma_one() directly instead of through
the dwc2_gadget_config_nonisoc_xfer_ddma() wrapper, which unconditionally
dereferenced the said pointer.
However, this was based on an incorrect assumption that in the context of
dwc2_hsotg_program_zlp() the pointer is always NULL, which is not the case.
The result were SB CV MSC tests failing starting from Test Case 6.
Instead, this patch reverts to calling the wrapper and adds a check for
the pointer being NULL inside the wrapper.

Insert a padding between data and the stored_xfer_buffer pointer to
ensure they are not on the same cache line.
Otherwise, the stored_xfer_buffer gets corrupted for IN URBs on
non-cache-coherent systems. (In my case: Lantiq xRX200 MIPS)

In commit abb621844f6a ("usb: ch9: make usb_endpoint_maxp() return
only packet size") the API to usb_endpoint_maxp() changed. It used to
just return wMaxPacketSize but after that commit it returned
wMaxPacketSize with the high bits (the multiplier) masked off. If you
wanted to get the multiplier it was now up to your code to call the
new usb_endpoint_maxp_mult() which was introduced in
commit 541b6fe63023 ("usb: add helper to extract bits 12:11 of
wMaxPacketSize").
Prior to the API change most host drivers were updated, but no update
was made to dwc2. Presumably it was assumed that dwc2 was too
simplistic to use the multiplier and thus just didn't support a
certain class of USB devices. However, it turns out that dwc2 did use
the multiplier and many devices using it were working quite nicely.
That means that many USB devices have been broken since the API
change. One such device is a Logitech HD Pro Webcam C920.
Specifically, though dwc2 didn't directly call usb_endpoint_maxp(), it
did call usb_maxpacket() which in turn called usb_endpoint_maxp().
Let's update dwc2 to work properly with the new API.

This patch fixes the chipmunk-like voice that manifets randomly when

The issue was solved initially for this device by commit 2394d67e446b

reintroduced by e387ef5c47dd ("usb: Add USB_QUIRK_RESET_RESUME for all

Xhci_handshake() implements the algorithm already captured by
readl_poll_timeout_atomic(). Convert the former to use the latter to
avoid repetition.
Turned out this patch also fixes a bug on the AMD Stoneyridge platform
where usleep(1) sometimes takes over 10ms.
This means a 5 second timeout can easily take over 15 seconds which will
trigger the watchdog and reboot the system.

xhci immediate data transfer (IDT) support in 5.2-rc1 caused regression
on various Samsung Exynos boards with ASIX USB 2.0 ethernet dongle.
If the transfer buffer in the URB is already DMA mapped then IDT should
not be used. urb->transfer_dma will already contain a valid dma address,
and there is no guarantee the data in urb->transfer_buffer is valid.
The IDT support patch used urb->transfer_dma as a temporary storage,
copying data from urb->transfer_buffer into it.
Issue was solved by preventing IDT if transfer buffer is already dma
mapped, and by not using urb->transfer_dma as temporary storage.

Tracking this down shows that udev->bos is NULL in the following code:
(xhci.c, in xhci_set_usb2_hardware_lpm)
field = le32_to_cpu(udev->bos->ext_cap->bmAttributes); <<<<<<< here
xhci_dbg(xhci, "%s port %d USB2 hardware LPM\n",
enable ? "enable" : "disable", port_num + 1);
if (enable) {
/* Host supports BESL timeout instead of HIRD */
if (udev->usb2_hw_lpm_besl_capable) {
/* if device doesn't have a preferred BESL value use a
* default one which works with mixed HIRD and BESL
* systems. See XHCI_DEFAULT_BESL definition in xhci.h
*/
if ((field & USB_BESL_SUPPORT) &&
(field & USB_BESL_BASELINE_VALID))
hird = USB_GET_BESL_BASELINE(field);
else
hird = udev->l1_params.besl;
The failing case is when disabling LPM. So it is sufficient to avoid
access to udev->bos by moving the instruction into the "enable" clause.

xhci_debugfs_create_endpoint()
In xhci_debugfs_create_slot(), kzalloc() can fail and
dev->debugfs_private will be NULL.
In xhci_debugfs_create_endpoint(), dev->debugfs_private is used without
any null-pointer check, and can cause a null pointer dereference.
To fix this bug, a null-pointer check is added in
xhci_debugfs_create_endpoint().
This bug is found by a runtime fuzzing tool named FIZZER written by us.

This change fixes a data corruption issue occurred on USB hard disk for
the case that bounce buffer is used during transferring data.
While updating data between sg list and bounce buffer, current
implementation passes mapped sg number (urb->num_mapped_sgs) to
sg_pcopy_from_buffer() and sg_pcopy_to_buffer(). This causes data
not get copied if target buffer is located in the elements after
mapped sg elements. This change passes sg number for full list to
fix issue.
Besides, for copying data from bounce buffer, calling dma_unmap_single()
on the bounce buffer before copying data to sg list can avoid cache issue.

stub_probe() and stub_disconnect() call functions which could call
sleeping function in invalid context whil holding busid_lock.
Fix the problem by refining the lock holds to short critical sections
to change the busid_priv fields. This fix restructures the code to
limit the lock holds in stub_probe() and stub_disconnect().

The syzkaller USB fuzzer found a slab-out-of-bounds write bug in the
USB core, caused by a failure to check the actual size of a BOS
descriptor. This patch adds a check to make sure the descriptor is at
least as large as it is supposed to be, so that the code doesn't
inadvertently access memory beyond the end of the allocated region
when assigning to dev->bos->desc->bNumDeviceCaps later on.

Instead of filling in the struct v4l2_capability device_caps
field, fill in the struct video_device device_caps field.
That way the V4L2 core knows what the capabilities of the
video device are.
But this only really works if all drivers use this, so convert
this UVC gadget driver.

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit 48f6e3cf5bc6
("kbuild: do not drop -I without parameter").

"SoC updates, mostly refactorings and cleanups of old legacy platforms.
Major themes this release:
- Conversion of ixp4xx to a modern platform (drivers, DT, bindings)
- Moving some of the ep93xx headers around to get it closer to
multiplatform enabled.
- Cleanups of Davinci
This also contains a few patches that were queued up as fixes before
5.1 but I didn't get sent in before release"

git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci into arm/soc
This update for DaVinci SoC support simplifies the VBUS enable
and overcurrent handling code in DA8XX OHCI driver by modeling
vbus GPIO as a regulator. This unifies code for all users, device
tree and non-device-tree.
The OHCI driver patches have been acked by its maintainer.

All users now setup a fixed regulator for the vbus supply. We can drop
the vbus GPIO code.

Historically the power supply management in this driver has been handled
in two separate places in parallel. Device-tree users simply defined an
appropriate regulator, while two boards with no DT support (da830-evm and
omapl138-hawk) passed functions defined in their respective board files
over platform data. These functions simply used legacy GPIO calls to
watch the oc GPIO for interrupts and disable the vbus GPIO when the irq
fires.
Commit d193abf1c913 ("usb: ohci-da8xx: add vbus and overcurrent gpios")
updated these GPIO calls to the modern API and moved them inside the
driver.
This however is not the optimal solution for the vbus GPIO which should
be modeled as a fixed regulator that can be controlled with a GPIO.
In order to keep the overcurrent protection available once we move the
board files to using fixed regulators we need to disable the enable_reg
regulator when the overcurrent indicator interrupt fires. Since we
cannot call regulator_disable() from interrupt context, we need to
switch to using a oneshot threaded interrupt.

There's no reason to have a separate variable to keep track of the
regulator state. The regulator core already does that. Remove
reg_enabled from struct da8xx_ohci_hcd.

We have two *_CLASS_DEVICE kernel config options (LCD_CLASS_DEVICE
and BACKLIGHT_LCD_DEVICE) that do the same job.
The patch removes useless BACKLIGHT_LCD_SUPPORT option
and converts LCD_CLASS_DEVICE into a menu.

Pull drm updates from Dave Airlie:
"This has two exciting community drivers for ARM Mali accelerators.
Since ARM has never been open source friendly on the GPU side of the
house, the community has had to create open source drivers for the
Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
series. Well done to all involved and hopefully this will help ARM
head in the right direction.
There is also now the ability if you don't have any of the legacy
drivers enabled (pre-KMS) to remove all the pre-KMS support code from
the core drm, this saves 10% or so in codesize on my machine.
i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
moves out of staging.
There are also some rcar-du patches which crossover with media tree
but all should be acked by Mauro.
