Subject: Re: [PATCH v4 00/14] Add RDMA memory mode support for mediatek SOC
 MT2712

Hi, Stu:

For the series, applied to mediatek-drm-next-4.19 [1], but I modified
'drm/mediatek: add RGB color format support for RDMA' and 'drm/mediatek:
add YUYV/UYVY color format support for RDMA' because I would like to
place related register definition together.

CK
