Subject: drm/msm: allow passing struct msm_kms to msm_drv_probe()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a2ab5d5bb6b1dedef7b6c2711a7a53cbf9f508f4;p=linux.git

drm/msm: allow passing struct msm_kms to msm_drv_probe()

In preparation of moving resource allocation to the probe time, allow
MSM KMS drivers to pass struct msm_kms pointer via msm_drv_probe().
