Hi Tiffany,
I get a bunch of warnings when I compile the decoder driver in my daily build
setup:
/home/hans/work/build/media-git/drivers/media/platform/mtk-vcodec/vdec/vdec_h264_if.c:

^^^^ Apparently a slab.h include is missing here that breaks building it with
sparse.
Can you look at these and provide a patch fixing these? I'll fold it in the
patch series.

Hans
