Cx23885 driver spamming dmesg

Hello, couldn’t find anything for my issue, adding new topic.

I’m running 5.11.6-1-MANJARO, using all latest updates. My box is MSI MAG X570 Tomahawk w/ AMD Ryzen 7 3700X.

My WinTV-QuadHD card is spamming my log with (apparently?) spurious messages at every boot (it used to happen once in a while… i would reboot and it wouldn’t happen. now it’s all the time). I say “apparently spurious” b/c it seems I can view & record TV shows normally.

I’ve googled others experiencing similar issues in the past, but there was no firm resolution to the issue aside from a workaround (debug=7 in cx23885 options) that doesn’t work for me.
I’ve even tried to use a different free pci slot, w/no success.
This box is being used as my Plex Server.

Appreciate any helps I can get. Here’s the messages that show up in dmesg each boot:
