Subject: scsi: smartpqi: mark PM functions as __maybe_unused
Patch-mainline: v4.13-rc1
Git-commit: 5c146686e32085e76ad9e2957f3dee9b28fe4f22
References: FATE#323891,bsc#1049514
The newly added suspend/resume support causes harmless warnings when
CONFIG_PM is disabled:
smartpqi/smartpqi_init.c:5147:12: error: 'pqi_ctrl_wait_for_pending_io' defined but not used [-Werror=unused-function]
smartpqi/smartpqi_init.c:2019:13: error: 'pqi_wait_until_lun_reset_finished' defined but not used [-Werror=unused-function]
smartpqi/smartpqi_init.c:2013:13: error: 'pqi_wait_until_scan_finished' defined but not used [-Werror=unused-function]
We can avoid the warnings by removing the #ifdef around the handlers and
instead marking them as __maybe_unused, which will let gcc drop the
unused code silently.
