Subject: [PATCH AUTOSEL for 3.18 29/59] video: fbdev: au1200fb: Release some
 resources if a memory allocation fails

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 451f130602619a17c8883dd0b71b11624faffd51 ]

We should go through the error handling code instead of returning -ENOMEM
directly.
