Subject: [PATCH 3/5] regulator: pwm: Prints error number when it fails
Date: Tue, 8 Mar 2016 16:23:23 +0530 [thread overview]
Message-ID: <1457434405-30372-4-git-send-email-ldewangan@nvidia.com> (raw)
In-Reply-To: <1457434405-30372-1-git-send-email-ldewangan-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>
Prints the error number along with error message when any
error occurs. This helps on getting the reason of failure
quickly from log without any code instrument.
