Subject: [PATCH 2/2] mfd: smsc-ece1099: Refactoring for smsc_i2c_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 29 Dec 2015 15:03:31 +0100

This issue was detected by using the Coccinelle software.

* Let us return directly if a call of the function "devm_regmap_init_i2c"
  or "regmap_write" failed.

* Delete the jump label "err" then.
