    Subject[PATCH 5.18 164/879] media: hantro: HEVC: unconditionnaly set pps_{cb/cr}_qp_offset values
    Date
    From: Benjamin Gaignard <benjamin.gaignard@collabora.com>

    [ Upstream commit 46c836569196f377f87a3657b330cffaf94bd727 ]

    Always set pps_cb_qp_offset and pps_cr_qp_offset values in Hantro/G2
    register whatever is V4L2_HEVC_PPS_FLAG_PPS_SLICE_CHROMA_QP_OFFSETS_PRESENT
    flag value.
    The vendor code does the same to set these values.
    This fixes conformance test CAINIT_G_SHARP_3.

    Fluster HEVC score is increase by one with this patch.
