A new helper function(__drm_atomic_helper_plane_reset) has been added for linking a plane with its state and resetting the core properties(alpha, rotation, etc.) to their default values. Use that instead of duplicating the logic.
__drm_atomic_helper_plane_reset initializes the alpha property to its max value, which is defined by the drm core as DRM_BLEND_ALPHA_OPAQUE, so nothing changes regarding the alpha value.
