[PATCH 09/24] iwlwifi: mvm: byte-swap constant instead of variable

From: Luca Coelho <hidden>
Date: 2017-07-28 14:24:12
Subsystem: intel wireless wifi link (iwlwifi), the rest · Maintainers: Miri Korenblit, Linus Torvalds

From: Johannes Berg <redacted>

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.
