From fddbeb80a904aae41c84ed566e2b0d1de55907df Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 2 Mar 2016 16:59:00 +0100 Subject: [PATCH] scsi: mvumi: use __maybe_unused to hide pm functions The mvumi scsi hides the references to its suspend/resume functions in an #ifdef but does not hide the implementation the same way: drivers/scsi/mvumi.c:2632:12: error: 'mvumi_suspend' defined but not used [-Werror=unused-function] drivers/scsi/mvumi.c:2651:12: error: 'mvumi_resume' defined but not used [-Werror=unused-function] This adds __maybe_unused annotations so the compiler knows it can silently drop them instead of warning, while avoiding the addition of another #ifdef.
