[v4,2/9] drm/tests: Add parameters to the drm_test_framebuffer_create test

Commit Message

Carlos Eduardo Gallo Filho Aug. 5, 2024, 11:39 p.m. UTC

Extend the existing test case to cover:
1. Invalid flag atribute in the struct drm_mode_fb_cmd2.
2. Pixel format which requires non-linear modifier with
DRM_FORMAT_MOD_LINEAR set.
3. Buffer offset for inexistent plane

v2:
  - Remove strcpy to strscpy change.
v3:
  - Rename and commment the "Buffer offset for inexistent plane"
    test case.
