Subject[PATCH 1/4] include/linux/suspend.h: Only show pm_pr_dbg messages at suspend/resume
Date
All uses in the kernel are currently already oriented around
suspend/resume. As some other parts of the kernel may also use these
messages in functions that could also be used outside of
suspend/resume, only enable in suspend/resume path.
