5c2ba8b85e rtl8712: pwrctrl_priv: Replace semaphore lock with mutex
The semaphore 'lock' in 'pwrctrl_priv' is used as a simple mutex, so it
should be written as one. Semaphores are going away in the future.
_enter_pwrlock was using down_interruptible(), so the lock could be broken
by sending a signal. This could be a bug, because nothing checks the return
code here. Hence, using mutex_lock instead of the interruptible version.
Removing the now unused _enter_pwrlock and _down_sema.

78ece0b945 staging: r8712u: Fix leak of skb
There are two types of messages queued for RX. The major type, which does
I/O on the device, was being handled properly. The skbs that communicated
with the firmware were being leaked.

While rewriting the code that sets up the skb, it was possible to remove
the private variable indicating that the old skb could be reused.

8c5af16f79 staging: rtl8712: reduce stack usage
The "translate_scan" function in rtl8712 uses a lot of stack, and
gets inlined into its single caller, r8711_wx_get_scan, which
in some configurations now blows the 1024 byte stack warning
limit:

drivers/staging/rtl8712/rtl871x_ioctl_linux.c: In function 'r8711_wx_get_scan':
drivers/staging/rtl8712/rtl871x_ioctl_linux.c:1227:1: error: the frame size of 1032 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

This somewhat reduces the stack usage by moving the translate_scan
function out of line with the noinline_for_stack annotation.
It might be possible to modify translate_scan() a little further
to reduce the stack usage, but with this patch, we can build without
the warning, the the call chain to get here is rather predictable
(sys_ioctl->vfs_ioctl->sock_ioctl->dev_ioctl->wext_ioctl->
r8711_wx_get_scan).

Fix this by handling the ENODEV error (during suspend) essentially by

aea48157ce staging: rtl8712: memory corruption in wpa_set_encryption()
->KeyMaterial is declared as a 16 byte array, but we only ever allocate
either 5 or 13 bytes of it.  The problem is that we memset() all 16
bytes to zero so we're memsetting past the end of the allocated memory.

I fixed this in slightly lazy way, by just allocating 16 bytes.  This
works but there is a lot more cleanup you could do to this code if you
wanted.  Which is why this code is in staging.

Use timer API function del_timer_sync instead of driver

a timer, it also ensures that the timer is stopped on all
CPUs before the driver exists. Also, variables
timer_cancelled and bool are removed as they are no longer

22905b8594 staging: rtl8712: replace memset(x,0,ETH_ALEN)
eth_zero_addr() is a wrapper function for memset if 0 is going to
be assigned to a mac address. The aforementioned function replaces
memset. In addition, linux/etherdevice.h was included as a header
since it is the file that defines the inline function eth_zero_addr().
The changes were carried out using the following coccinelle script:
