Subject: [PATCH] staging: rtl8723bs: do not use __constant_cpu_to_le16
Date: Thu, 14 Mar 2019 17:31:55 +0900 [thread overview]
Message-ID: <20190314083155.23164-1-sergey.senozhatsky@gmail.com> (raw)
A trivial patch.
cpu_to_le16() is capable enough to detect __builtin_constant_p()
and to use an appropriate compile time ___constant_swahbXX()
function.
So we can use cpu_to_le16() instead of __constant_cpu_to_le16().
