drm/imx/dcss: Initialize DRM driver instance with CMA helper macro (80cf656c) · Commits · 戴 / test

The i.MX DCSS driver uses CMA helpers with default callback functions. Initialize the driver structure with the rsp CMA helper macro. The driver is being converted to use GEM object functions as part of this change. Two callbacks, .gem_prime_export and .gem_prime_import, were initialized to their default implementations, so they are just kept empty now. Signed-off-by:
