From 4d32d0476906e1451cbcb91e88320134a4b890b7 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Thu, 19 Dec 2013 09:23:08 +0100 Subject: [PATCH] video: mx3fb: Allow blocking during framebuffer allocation 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.
