4.19-stable review patch. If anyone has any objections, please let me know. ------------------ From: Jani Nikula <jani.nikula@xxxxxxxxx> [ Upstream commit c2da9ada64962fcd2e6395ed9987b9874ea032d3 ] The .get_modes() hooks aren't supposed to return negative error codes. Return 0 for no modes, whatever the reason.
