Subject[PATCH 1/3] [media] camss-csid: Use common error handling code in csid_set_power()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 23 Sep 2017 20:48:33 +0200

Add jump targets so that a bit of exception handling can be better reused
at the end of this function.

This issue was detected by using the Coccinelle software.
