When not associated with an AP, wifi device drivers should respond to the
SIOCGIWESSID ioctl with a zero-length string for the SSID, which is the
behavior expected by dhcpcd.
Currently, this driver returns an error code (-1) from the ioctl call,
which causes dhcpcd to assume that the device is not a wireless interface
and therefore it fails to work correctly with it thereafter.
This problem was reported and tested at
https://github.com/lwfinger/rtl8188eu/issues/234.

Commit 2ba8444c97b1 ("staging:r8188eu: move IV/ICV trimming into
decrypt() and also place it after rtl88eu_mon_recv_hook()") breaks ARP.
After this commit ssh-ing to a laptop with r8188eu wifi no longer works
if the machine connecting has never communicated with the laptop before.
This is 100% reproducable using "arp -d <ipv4> && ssh <ipv4>" to ssh to
a laptop with r8188eu wifi.
This commit reverts 4 commits in total:
1. Commit 79650ffde38e ("staging:r8188eu: trim IV/ICV fields in
validate_recv_data_frame()")
This commit depends on 2 of the other commits being reverted.
2. Commit 02b19b4c4920 ("staging:r8188eu: inline unprotect_frame() in
mon_recv_decrypted_recv()")
The inline code is wrong the un-inlined version contains:
if (skb->len < hdr_len + iv_len + icv_len)
return;
...
Where as the inline-ed code introduced by this commit does:
if (skb->len < hdr_len + iv_len + icv_len) {
...
Note the same check, but now to actually continue doing ... instead
of to not do it, so this commit is no good.
3. Commit d86e16da6a5d ("staging:r8188eu: use different mon_recv_decrypted()
inside rtl88eu_mon_recv_hook() and rtl88eu_mon_xmit_hook().")
This commit introduced a 1:1 copy of a function so that one of the
2 copies can be modified in the 2 commits we're already reverting.
4. Commit 2ba8444c97b1 ("staging:r8188eu: move IV/ICV trimming into
decrypt() and also place it after rtl88eu_mon_recv_hook()")
This is the commit actually breaking ARP.
Note this commit is a straight-forward squash of the revert of these
4 commits, without any changes.

A common pattern with skb_put() is to just want to memcpy()

Network devices can allocate reasources and private memory using
netdev_ops->ndo_init(). However, the release of these resources
can occur in one of two different places.
Either netdev_ops->ndo_uninit() or netdev->destructor().
The decision of which operation frees the resources depends upon
whether it is necessary for all netdev refs to be released before it
is safe to perform the freeing.
netdev_ops->ndo_uninit() presumably can occur right after the
NETDEV_UNREGISTER notifier completes and the unicast and multicast
address lists are flushed.
netdev->destructor(), on the other hand, does not run until the
netdev references all go away.
Further complicating the situation is that netdev->destructor()
almost universally does also a free_netdev().
This creates a problem for the logic in register_netdevice().
Because all callers of register_netdevice() manage the freeing
of the netdev, and invoke free_netdev(dev) if register_netdevice()
fails.
If netdev_ops->ndo_init() succeeds, but something else fails inside
of register_netdevice(), it does call ndo_ops->ndo_uninit(). But
it is not able to invoke netdev->destructor().
This is because netdev->destructor() will do a free_netdev() and
then the caller of register_netdevice() will do the same.
However, this means that the resources that would normally be released
by netdev->destructor() will not be.
Over the years drivers have added local hacks to deal with this, by
invoking their destructor parts by hand when register_netdevice()
fails.
Many drivers do not try to deal with this, and instead we have leaks.
Let's close this hole by formalizing the distinction between what
private things need to be freed up by netdev->destructor() and whether
the driver needs unregister_netdevice() to perform the free_netdev().
netdev->priv_destructor() performs all actions to free up the private
resources that used to be freed by netdev->destructor(), except for
free_netdev().
netdev->needs_free_netdev is a boolean that indicates whether
free_netdev() should be done at the end of unregister_netdevice().
Now, register_netdevice() can sanely release all resources after
ndo_ops->ndo_init() succeeds, by invoking both ndo_ops->ndo_uninit()
and netdev->priv_destructor().
And at the end of unregister_netdevice(), we invoke
netdev->priv_destructor() and optionally call free_netdev().

Since commit da25a8ec6b2d ("staging: rtl8188eu: remove unused

value, so it is actually always zero.
It is also used only once, as a boolean inside an if(). This means the
code under that if() is dead code, so remove it as well.

Pull staging/IIO updates from Greg KH:
"Here's the "big" staging/iio pull request for 4.10-rc1.
Not as big as 4.9 was, but still just over a thousand changes. We
almost broke even of lines added vs. removed, as the slicoss driver
was removed (got a "clean" driver for the same hardware through the
netdev tree), and some iio drivers were also dropped, but I think we
ended up adding a few thousand lines to the source tree in the end.
Other than that it's a lot of minor fixes all over the place, nothing
major stands out at all.
All of these have been in linux-next for a while. There will be a
merge conflict with Al's vfs tree in the lustre code, but the
resolution for that should be pretty simple, that too has been in
linux-next"

The test for NULL of the return variable of functions was changed from
(ret == NULL) to !ret to match the standard.
Coccinelle was used with semantic patch:

expression e;
identifier id, f;
statement S;
@@
f(...) { <+...
id =
\(kmalloc\|devm_kzalloc\|kmalloc_array\|devm_ioremap
\|usb_alloc_urb\|alloc_netdev\|dev_alloc_skb\) (...)
... when any
when != id = e
+ if (!id)
- if (\(NULL == id\|id == NULL\))
S
