From: Greg Kroah-Hartman
Date: Mon Aug 15 2022 - 17:05:05 EST


From: Benjamin Gaignard <benjamin.gaignard@xxxxxxxxxxxxx>

[ Upstream commit 300065f966d30baa59a13849753305aac8c320c3 ]

Documentation said that g2 init_qp field use bits 24 to 30 of
the 8th register.
Change the field mask to be able to set 7 bits and not only 6 of them.

Conformance test INITQP_B_Main10_Sony_1 decoding is OK with this
patch.
