Arnd Bergmann 0c9f3a65c5 staging: rtl8712, rtl8712: avoid lots of build warnings
The rtl8712 driver has an 'extern inline' function that contains an
'if', which causes lots of warnings with CONFIG_PROFILE_ALL_BRANCHES
overriding the definition of 'if':

drivers/staging/rtl8712/ieee80211.h:759:229: warning: '______f' is static but declared in inline function 'ieee80211_get_hdrlen' which is not static [enabled by default]

This changes the driver to use 'static inline' instead, which happens
to be the correct annotation anyway.

Vitaly Osipov 91d435fe36 staging: rtl8712: remove _malloc()
This patch removes all usage of _malloc() and the function itself. Most
uses are straightforward replacements by kmalloc(..., GFP_ATOMIC),
because this was the definition of _malloc(). In a few places it
was possible to use kzalloc() or memdup_user.

A further improvement would be to replace GFP_ATOMIC with GFP_KERNEL
where possible.

Verified by compilation only.

Initial replacement done by running a Coccinelle script along the lines
of:

@@
type T;
expression E;
identifier V;
@@
- V = (T) _malloc(E);
+ V = kmalloc(E, GFP_ATOMIC);

@@
