Subject: drm: rcar-du: Pass the encoder DT node to rcar_du_encoder_init()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3ea4d5ec68fa5dc489ee1e4fe3ff07e4ddf0459d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm: rcar-du: Pass the encoder DT node to rcar_du_encoder_init()

The encoder DT node will be needed to register an external HDMI encoder.
Pass it to the rcar_du_encoder_init() function to prepare for HDMI
support.
