6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lijo Lazar <lijo.lazar@xxxxxxx>
[ Upstream commit 8c50bf9beb889fd2bdcbf95b27a5d101eede51fc ]
EXTERNAL_REG_INTERNAL_OFFSET/EXTERNAL_REG_WRITE_ADDR should be used in
pairs. If an external register shouldn't be written, both packets
shouldn't be sent.
Fixes: a78b48146972 ("drm/amdgpu: Skip PCTL0_MMHUB_DEEPSLEEP_IB write in jpegv4.0.3 under SRIOV")
