[PATCH AUTOSEL for 4.4 055/101] video: fbdev: au1200fb: Return an error code if a memory allocation fails

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 8cae353e6b01ac3f18097f631cdbceb5ff28c7f3 ]

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