[PATCH 14/24] ste_dma40: One check less in d40_prep_sg() after error detection

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Sat, 17 Sep 2016 15:34:07 +0200

* Adjust jump targets according to the Linux coding style convention.

* Delete a repeated check which became unnecessary with this refactoring.
