I picked the four patches in this series into my rockchip-7.2.y kernel
branch [0] and compile failed. Claude Opus suggested fixes [1] which
allowed compile to succeed. Sadly I've no idea if the changes resulted
in a working driver as I've enthusiastically powered up a Radxa Rock4D
board and rediscovered its AIC8800 is connected via USB not SDIO; but I
figured I'd share the finding anyway, in case it's valid.

Keep up the good work, I look forward to USB support in the future!
