[PATCH 04/24] ste_dma40: Move an assignment in d40_lcla_allocate()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sat, 17 Sep 2016 08:24:46 +0200

Move one assignment for the local variable "ret" so that its setting
will only be performed after corresponding data processing succeeded
by this function.
