4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <a...@arndb.de>
commit fddbeb80a904aae41c84ed566e2b0d1de55907df upstream.
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.
