Subject: drm/msm/adreno: slight init order cleanup
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0122f96fc2c1f911cb5b4db0a6dc98ac367e7e44;p=linux-beck.git

drm/msm/adreno: slight init order cleanup

Move anything that can fail after call to base class msm_gpu_init().
This way, if we fail, active_list has already been initialized so we
don't trip 'WARN_ON(!list_empty(&gpu->active_list))' in
msm_gpu_cleanup().
