X-Git-Tag: v4.19~2168^2~281 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5bca178eed601cd4584c38c5290f7abbcacf3fb3;p=platform%2Fkernel%2Flinux-rpi.git net: faraday: ftmac100: Use BUG_ON instead of if condition followed by BUG. Notice that in this particular case unlikely() is already being called inside BUG_ON macro. This issue was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R.
