drm/tests: hdmi: Fix memory leaks in drm_display_mode_from_cea_vic()

2024-10-31T09:31:35+00:00

modprobe drm_hdmi_state_helper_test and then rmmod it, the following
memory leak occurs.

The `mode` allocated in drm_mode_duplicate() called by
drm_display_mode_from_cea_vic() is not freed, which cause the memory leak:

drm/tests: helpers: Add helper for drm_display_mode_from_cea_vic()

2024-10-31T09:31:34+00:00

As Maxime suggested, add a new helper
drm_kunit_display_mode_from_cea_vic(), it can replace the direct call
of drm_display_mode_from_cea_vic(), and it will help solving
the `mode` memory leaks.

2024-09-11T12:17:10+00:00

Add three KUnit test cases for the drm_framebuffer_init function:

1. Test if expected values are being set after drm_framebuffer_init() call.
2. Try to init a framebuffer without setting its format.
3. Try calling drm_framebuffer_init() with mismatch of the drm_device
   passed at the first argument and the one pointed by fb->dev.

Add two KUnit test cases for the drm_framebuffer_lookup function, one
for the base case, that tests if the lookup finds the correct framebuffer
object and another that tests the lookup for an inexistent framebuffer.
