Subject: [PATCH 6/6] mfd: smsc-ece1099: Return directly after a function
 failure in smsc_i2c_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 26 Jun 2016 14:30:46 +0200

This issue was detected by using the Coccinelle software.

Return directly if a call of the function "devm_regmap_init_i2c"
or "regmap_write" failed.

Delete the jump label "err" then.
