I'm getting these compile warnings/errors:
drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c: In function ‘mtk_jpeg_enc_device_run’:

It's indeed not used.

This apparently relies on https://lore.kernel.org/linux-arm-kernel/20191204124732.10932-2-Jerry-Ch.chen@xxxxxxxxxxxx/
Please add this patch to this series. Don't forget to add Tomasz' 'Reviewed-by' line.

This is definitely wrong. A break is missing here.
