drm: rcar-du: Remove inclusion of drmP.h (9a47db8e) · Commits · 戴 / test

The DRM kernel API used to be defined in a handful of headers, pulled in through drmP.h. It has since been split in multiple headers for the different DRM components, and drmP.h turned into a legacy header that just pulls in most of the DRM kernel API (and a large number of other miscellaneous kernel headers). In order to speed up compilation, replace inclusion of drmP.h with only the required headers. It turns out that the rcar-du-drm driver already includes most of the necessary headers, so the change is simple. While at it, remove unneeded inclusion of other headers, and unneeded forward declarations of structures. Signed-off-by:
