From: Build regressions/improvements in v3.3-rc3

Fellow wireless developers:

In http://lkml.indiana.edu/hypermail/linux/kernel/1202.1/01964.html, Geert 
Uytterhoeven lists the following warnings as occurring in mainline V3.3-rc3. The 
list is considerably smaller than were found for V3.2. In addition, there are no 
longer any build errors for wireless.

I'm pretty sure the remaining warnings are not present in the current 
wireless-testing code using "gcc (SUSE Linux) 4.6.2", but I'm posting them so 
that you know some compiler/architecture combination reports a problem. The 
warnings are as follows:

+ src/drivers/net/wireless/ath/ath5k/base.c: warning: return from incompatible 
pointer type: => 84, 85:1
+ src/drivers/net/wireless/ath/ath6kl/init.c: warning: 'hw' may be used 
uninitialized in this function: => 1377:26

uninitialized in this function: => 915
