No, I should remove it. and also would like to update as following:

        depends on VIDEO_V4L2
        depends on ARCH_MEDIATEK || COMPILE_TEST
        select VIDEOBUF2_DMA_CONTIG
        select VIDEOBUF2_CORE
        select VIDEOBUF2_V4L2
        select VIDEOBUF2_MEMOPS
        select MEDIA_CONTROLLER
        select MTK_SCP

Typo fixed.

I will refine as:
Support the Face Detection (FD) feature in the Mediatek mt8183 Soc.

Thanks and best regards,
