Subject: [PATCH] Input: zforce_ts - use devm_add_action_or_reset()
Date: Sun,  3 Jul 2016 21:48:46 +0100	[thread overview]
Message-ID: <1467578926-32297-1-git-send-email-sudipm.mukherjee@gmail.com> (raw)

If devm_add_action() fails we are explicitly calling the cleanup to free
the resources allocated.  Lets use the helper devm_add_action_or_reset()
and return directly in case of error, as we know that the cleanup function
has been already called by the helper if there was any error.
