[PATCH] drm/komeda: Remove useless variable assignment

[PATCH] drm/komeda: Remove useless variable assignment

[carsten.haitzler]

From: Carsten Haitzler <carsten.haitzler@arm.com>

ret is not actually read after this (only written in one case then
returned), so this assign line is useless. This removes that assignment.
