Hi All, I have updated the second patch to first try allocating the DMA buffer with a 32-bit mask. If that fails and the host supports a 64-bit msi_msg buffer, then the driver will retry the allocation with a 64-bit DMA mask. I rebased the series and tested with a Pixel 6 on 6.0-rc1 (android-mainline) and a db845c with 5.15. Thanks for the reviews!
