[PATCH 13/17] spi/topcliff-pch: Delete an unnecessary return statement in two functions

Show all headers | View raw

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 13 Jan 2017 15:57:03 +0100

The script "checkpatch.pl" pointed information out like the following.

WARNING: void function return statements are not generally useful

Thus remove such statements here.
