Subject[PATCH 4.4 071/115] video: fbdev: au1200fb: Return an error code if a memory allocation fails
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

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


[ Upstream commit 8cae353e6b01ac3f18097f631cdbceb5ff28c7f3 ]

'ret' is known to be 0 at this point.
In case of memory allocation error in 'framebuffer_alloc()', return
-ENOMEM instead.
