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 a driver hang caused by earlier suspend/resume cycles. By handling a

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

->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.
