From 5c146686e32085e76ad9e2957f3dee9b28fe4f22 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 18 May 2017 10:32:18 +0200 Subject: [PATCH] scsi: smartpqi: mark PM functions as __maybe_unused 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.
