[PATCH v3 1/6] pwm: print error messages with pr_err() instead of pr_debug()

From: Bhuvanchandra DV
Date: Fri Oct 07 2016 - 14:46:28 EST


From: Lothar Wassmann <LW@xxxxxxxxxxxxxxxxxxx>

Make the messages that are printed in case of fatal errors actually
visible to the user without having to recompile the driver with
debugging enabled.
