Subject: [PATCH] Input-max8925_onkey: Use common error handling code in
 max8925_onkey_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>

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.
