Subject: staging: rtl8723bs: change custom comparing function to strcmp()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=97eef87a546e665f62c4c5500b2381a3c90c0ef1;p=thirdparty%2Flinux.git

staging: rtl8723bs: change custom comparing function to strcmp()

eqNByte() function is a redundant reimplementation of strcmp().
Remove eqNByte() and switch its usages to strcmp().
No functional change.
