[ Upstream commit 4d486f18d91b1876040bf87e9ad78981a08b15a6 ]
We return 0 unconditionally in 'rcar_du_crtc_set_crc_source()'.
However, 'ret' is set to some error codes if some function calls fail.
Return 'ret' instead to propagate the error code.
Fixes: 47a52d024e89 ("media: drm: rcar-du: Add support for CRC computation")
