Subject: drm/msm/dpu: remove pipe_qos_cfg from struct dpu_plane
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b243c8c0156dd28ca8972b88b67a2e3bca768493;p=linux.git

drm/msm/dpu: remove pipe_qos_cfg from struct dpu_plane

The pipe_qos_cfg is used only in _dpu_plane_set_qos_ctrl(), so remove it
from the dpu_plane struct and allocate it on stack when necessary.
