[PATCH 5.10 232/452] media: rkvdec: h264: Fix bit depth wrap in pps packet

[Greg Kroah-Hartman]

From: Jonas Karlman <jonas@xxxxxxxxx>

[ Upstream commit a074aa4760d1dad0bd565c0f66e7250f5f219ab0 ]

The luma and chroma bit depth fields in the pps packet are 3 bits wide.
8 is wrongly added to the bit depth values written to these 3 bit fields.
Because only the 3 LSB are written, the hardware was configured
correctly.

Correct this by not adding 8 to the luma and chroma bit depth value.
