    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.
