Move aperture management out of the fbdev code. It is unrelated and needs to run even if fbdev support has been disabled. Call the helper at the top of msm_drm_init() to take over hardware from other drivers. v2: * bind all subdevices before acquiring device (Dmitri) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> --- drivers/gpu/drm/msm/msm_drv.c | 6 ++++++ drivers/gpu/drm/msm/msm_fbdev.c | 6 ------ 2 files changed, 6 insertions(+), 6 deletions(-)
