From 0a5d79bfc0154bb587d5a439dc0e439d4d72f25b Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Fri, 27 Oct 2017 17:20:45 +0200 Subject: mfd: ab8500-debugfs: Use common error handling code in ab8500_print_modem_registers() Add jump targets so that two error messages are stored only once at the end of this function implementation. This issue was detected by using the Coccinelle software.
