Souptick Joarder bd4fcdaddc staging : rtl8712: Free memory when kmalloc fails
There are few functions where we need to free previously allocated
memory when kmalloc fails. Else it may lead to memory leakage. In
_init_cmd_priv() and _r8712_init_xmit_priv(), in few places we are
not freeing previously allocated memory when kmalloc fails.

Zach Brown 0c1d83c495 staging: rtl8712: Change _LED_STATE enum in rtl871x driver to avoid conflicts with LED namespace
Adding led support for phy causes namespace conflicts for some
phy drivers.

The rtl871 driver declared an enum for representing LED states. The enum
contains constant LED_OFF which conflicted with declaration found in
linux/leds.h. LED_OFF changed to LED_STATE_OFF
In order to avoid a possible future collision LED_ON was changed to
LED_STATE_ON as well.

Matthew Kilgore 8681a1d47b Fixes: 3d44a78f0d ("staging: rtl8712: Remove unnecessary 'else'")
An "unnecessary" 'else' was removed due to complains from checkpatch.pl
as it is preceded by a 'return', however the 'else' branch is necessary
as an earlier branch of the 'if' falls through. By removing the 'else',
that route now hits the 'break' and the 'while' loop exits prematurely.

This commit reverts that change and puts the original 'else' back in
place.

Binoy Jayan 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.

While rewriting the code that sets up the skb, it was possible to remove
