Subject: drm/mode: move framebuffer_free up above framebuffer_init
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=f55f1f91f567ac32cbf04fbdd455fc54661504fb;p=openwrt%2Fstaging%2Fblogic.git

drm/mode: move framebuffer_free up above framebuffer_init

A later patch will use it in framebuffer_init, and I want
to keep the diff cleaner.
