Hi Folks,
I am getting the following dmesg during shutdown on a stable kernel
(5.15.90) on a sunxi-a20 board.
Please consider cherry-pick the following commits to fix the issue in
stable kernel
09b343038e34 ("i2c: mv64xxx: Remove shutdown method from driver")
544a8d75f3d6 ("i2c: mv64xxx: Add atomic_xfer method to driver")
Thanks and have a good one,
- Tong
