scsi: smartpqi: mark PM functions as __maybe_unused

2017-06-13T00:48:05+00:00

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.
