[PATCH] drm/imx/dcss: include drm/drm_bridge.h header

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

Compile-testing random configurations leads to failures in
dcss-kms.c from a missing declaration:

drivers/gpu/drm/imx/dcss/dcss-kms.c:95:8: error: use of undeclared identifier 'drm_bridge_attach'
   95 |         ret = drm_bridge_attach(encoder, bridge, NULL,
      |               ^
drivers/gpu/drm/imx/dcss/dcss-kms.c:96:5: error: use of undeclared identifier 'DRM_BRIDGE_ATTACH_NO_CONNECTOR'
   96 |                                 DRM_BRIDGE_ATTACH_NO_CONNECTOR);
      |                                 ^

Include the header directly.

Fixes: 004555a18d57 ("drm/imx/dcss: Allow build with COMPILE_TEST=y")

Unfortunately, it appears I lost drm-misc push rights. Maxime, Thomas or
Ville, can you help push this?

Thanks,
Laurentiu

I can pick it up.

However I think it is:

Fixes: e7033bdfd43b ("drm/imx/dcss: use drm_bridge_connector API")

With that

It's probably both commits. My randconfig builds showed it only
failing on x86, which means that it was still working by
accident on all builds that include ARCH_MXC && ARM64, between
the two commits. The commit you pointed out should have added
the #include, but that seems to come indirectly from
include/drm/drm_of on all arm64 builds.
