Merge tag 'char-misc-5.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc driver updates from Greg KH: "Here is the big char/misc driver patch pull request for 5.1-rc1. The largest thing by far is the new habanalabs driver for their AI accelerator chip. For now it is in the drivers/misc directory but will probably move to a new directory soon along with other drivers of this type. Other than that, just the usual set of individual driver updates and fixes. There's an "odd" merge in here from the DRM tree that they asked me to do as the MEI driver is starting to interact with the i915 driver, and it needed some coordination. All of those patches have been properly acked by the relevant subsystem maintainers. All of these have been in linux-next with no reported issues, most for quite some time" * tag 'char-misc-5.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (219 commits) habanalabs: adjust Kconfig to fix build errors habanalabs: use %px instead of %p in error print habanalabs: use do_div for 64-bit divisions intel_th: gth: Fix an off-by-one in output unassigning habanalabs: fix little-endian<->cpu conversion warnings habanalabs: use NULL to initialize array of pointers habanalabs: fix little-endian<->cpu conversion warnings habanalabs: soft-reset device if context-switch fails habanalabs: print pointer using %p habanalabs: fix memory leak with CBs with unaligned size habanalabs: return correct error code on MMU mapping failure habanalabs: add comments in uapi/misc/habanalabs.h habanalabs: extend QMAN0 job timeout habanalabs: set DMA0 completion to SOB 1007 habanalabs: fix validation of WREG32 to DMA completion habanalabs: fix mmu cache registers init habanalabs: disable CPU access on timeouts habanalabs: add MMU DRAM default page mapping habanalabs: Dissociate RAZWI info from event types misc/habanalabs: adjust Kconfig to fix build errors ...
