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

From: Sascha Hauer
Date: Thu Dec 19 2013 - 03:23:18 EST


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.
