I'm working on a related patch. Could you, please, describe your
use case for the spidev driver, i.e. what board are you using it on,
and for what purpose?
The board is ROCK64 and the purpose is to update all the software that
board runs, which is stored on the SPI NOR flash onboard.
I have not tested this kernel version on RK3399, but it may also
affect that other use case:
