Hi Rajendra,

After applying 2,3 and 4/5 patches on linaro-integration v5.8-rc2 I see
below messages on db845:

qcom-venus aa00000.video-codec: dev_pm_opp_set_rate: failed to find
current OPP for freq 533000097 (-34)

^^^ This one is new.

qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x30000

^^^ and this message is annoying, can we make it pr_debug in rpmh?
