From: Johannes Berg Date: Wed, 7 Jun 2017 07:31:13 +0000 (+0200) Subject: iwlwifi: mvm: byte-swap constant instead of variable X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c67a3d05024fad00ac160e868967a1e711073993;p=openwrt%2Fstaging%2Fblogic.git iwlwifi: mvm: byte-swap constant instead of variable Convention has it to byte-swap the constant instead of the variable when doing bit checks. This also generates better code when the swap is actually needed, since the constant can be swapped at compile-time.
