Linux regressions report for mainline [2022-10-02]

Hi Linus! Below is a slightly edited report from regzbot listing all
regression from this cycle that the bot and I are currently aware of.

Nothing really new since Friday. The fix for a NULL pointer dereference
on the arm64/rock960 (f340ed8664a5 ("phy: rockchip-inno-usb2: Return
zero after otg sync")) didn't make it to you yet afaics.

The Turris Omnia (Armada 385) issue apparently needs more time to debug.

The discussion about the kernel change that exposed a iomap bug in Qemu
is ongoing, not sure if a revert here would be the right solution for
now; check the thread for details.

There is a bug in 5.19.y that seems to cause trouble for quite some
people on the latest Framework laptops (
). Apparently the problem is caused by a backport of a recent mainline
commit, but one user reported that mainline is working fine.

HTH, Ciao, Thorsten
