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. Non-zero buffer offset for an unused plane Also replace strcpy to strscpy on test_to_desc for improved security and reliability.
