tpm/tpm_crb: fix unused warnings on suspend/resume functions
When PM_SLEEP is disabled crb_pm_suspend and crb_pm_resume are not used by
SET_SYSTEM_SLEEP_PM_OPS even if PM is enabled:
drvers/char/tpm/tpm_crb.c:540:12: warning: ‘crb_pm_suspend’ defined but not
used [-Wunused-function]
static int crb_pm_suspend(struct device *dev)
^
drivers/char/tpm/tpm_crb.c:551:12: warning: ‘crb_pm_resume’ defined but not
used [-Wunused-function]
static int crb_pm_resume(struct device *dev)
^
The preprocessor condition should be on CONFIG_PM_SLEEP, not on CONFIG_PM.
However, this patch fixes this warning by using __maybe_unused on function
that are in the preprocessor condition.
Fixes: 848efcfb560c ("tpm/tpm_crb: enter the low power state upon device suspend")
