Subject: ath9k: Use ARRAY_SIZE macro
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=896cbefadf62b431cba469089cc3bd5ecfe69ed5;p=openwrt%2Fstaging%2Fblogic.git

ath9k: Use ARRAY_SIZE macro

Use ARRAY_SIZE macro, rather than explicitly coding some variant of it
yourself.
Found with: find -type f -name "*.c" -o -name "*.h" | xargs perl -p -i -e
's/\bsizeof\s*\(\s*(\w+)\s*\)\s*\ /\s*sizeof\s*\(\s*\1\s*\[\s*0\s*\]\s*\)
/ARRAY_SIZE(\1)/g' and manual check/verification.
