Subject: drm/dsi: Do not require .owner field to be set
X-Git-Tag: firefly_0821_release~176^2~2672^2~63^2~1
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=99035e99310a5e779b0b8f44c7d3f5814fd2ec9c;p=firefly-linux-kernel-4.4.55.git

drm/dsi: Do not require .owner field to be set

Drivers now no longer need to set the .owner field. It will be
automatically set at registration time.
