Subject: add -Wunused-but-set-variable
X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;h=7f95fac61c96c91198ad65198c2fa30dfc936286;p=open-ath9k-htc-firmware.git

add -Wunused-but-set-variable

we can't just now use -Wall. So lets add them step by step.
-Wunused-but-set-variable seems to be a good start :)
