commit cf3591e upstream. Revert the commit bd293d0. The proper fix has been made available with commit d0a255e ("loop: set PF_MEMALLOC_NOIO for the worker thread"). Note that the fix offered by commit bd293d0 doesn't really prevent the deadlock from occuring - if we look at the stacktrace reported by Junxiao Bi, we see that it hangs in bit_wait_io and not on the mutex - i.e. it has already successfully taken the mutex. Changing the mutex from mutex_lock to mutex_trylock won't help with deadlocks that happen afterwards.

ROC-RK3399-PC has 3 USB ports (HOST0, HOST1, HOST2).
HOST0 and HOST1 ports are working but HOST2 is not.
(I have tested with firefly rk3399 BSP, linux-rockchip and linux-next kernel)
Any kind of help is appreciated.
