Subject: [PATCH 1/2] ARM: OMAP3: Use common error handling code in
 omap3xxx_hwmod_init()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 20 Oct 2017 16:30:23 +0200

Add a jump target 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.
