[PATCH v2,5/5] media: mediatek: vcodec: fix incorrect sizeimage for 10bit bitstream

From: Yunfei Dong
Date: Tue Apr 09 2024 - 02:46:13 EST


The sizeimage of each plane is calculated the same way for 8bit and
10bit bitstream. Using v4l2 common interface v4l2_fill_pixfmt_mp to
separate.

Fixes: 9d86be9bda6c ("media: mediatek: vcodec: Add driver to support 10bit")
