From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
commit a60ec4485f1c72dfece365cf95e6de82bdd74300 upstream.
Before the refactoring the pr_warn() only triggered when
someone explicitly tried to write to a BIOS locked limit.
After the refactoring the warning is also triggering during
system resume. The user can't do anything about this so
printing scary warnings doesn't make sense
Keep the printk but make it pr_debug() instead of pr_warn()
to make it clear it's not a serious issue.
