[PATCH] Input-mpr121: Use common error handling code in mpr_touchkey_interrupt()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Thu, 26 Oct 2017 21:16:53 +0200

Add a jump target so that an error message can be better reused
in an if branch of this function.

This issue was detected by using the Coccinelle software.
