[PATCH] video: mx3fb: Allow blocking during framebuffer allocation

From: Sascha Hauer <s.hauer@pengutronix.de>
Date: 2013-12-19 08:23:15
Also in: lkml
Subsystem: framebuffer layer, the rest · Maintainers: Helge Deller, Linus Torvalds

No need to allocate the framebuffer from the atomic pool, we are not
in interrupt context. Adding GFP_KERNEL to the framebuffer allocation
allows to use the much bigger CMA pool to allocate the framebuffer.
