Hello! Just a heads up to this report https://gitlab.freedesktop.org/drm/amd/-/issues/1850
Basically, after waking up on suspend there're freezes in apps using amdgpu, and there's a spam in syslog `Fence fallback timer expired on ring …`.
I bisected that to a commit
5a7b95fb993ec399c8a685552aa6a8fc995c40bd i2c: core: support bus regulator controlling in adapter
Since the commit is not in AMDGPU, I send this email to linux-i2c. The commit author CCed as well.
Should I send a revert, or is there a way to fix this?

Btw, please keep me on CC as I am not subscribed to the lists

You are the second one to report this problem and so far, there has been
no response from the authors. I will prepare a revert and CC all
involved people. Thank you for the nagging!
