Subject: [PATCH 2/5] drivers/video/bf54x-lq043fb.c: use devm_ functions

From: Damien Cassou <damien.cassou@...l.fr>

The various devm_ functions allocate memory that is released when a driver
detaches. This patch replaces the use of kzalloc by devm_kzalloc.

Signed-off-by: Damien Cassou <damien.cassou@...l.fr>
