drm/tests: bridge: convert to devm_drm_bridge_alloc() API2025-06-06T13:50:21+00:00Luca Ceresoliluca.ceresoli@bootlin.com2025-06-06T08:41:19+00:00urn:sha1:1ee7e69292a6f296b2d78393ab409a5bdd65d4e0
Use the new DRM bridge allocation API, which is the only supported now, for
the kunit tests.
This change is more massive than for the typical DRM bridge driver because
struct drm_bridge_init_priv currently embeds a struct drm_bridge, which is
not supported anymore. We now have to use devm_drm_bridge_alloc() to
dynamically allocate a "private driver struct", which is a bit awkward here
because there is no real bridge driver. Thus let's add a "dummy" DRM bridge
struct to represent it.
As a nice cleanup we can now move the enable_count and disable_count
members, which are counting bridge-specific events, into the new "private
driver struct" (and avoid adding new unnecessary indirections).
Also add a trivial bridge_to_dummy_bridge() function just like many drivers
do.

Let's provide a bunch of kunit tests to make sure
drm_bridge_helper_reset_crtc() works as expected.

None of the drm_bridge function have kunit tests so far. Let's change
that, starting with drm_bridge_get_current_state().
