[PATCH 4.14 0/8] uio backport fixes for 4.14

[Rantala, Tommi T. (Nokia - FI/Espoo)]

Backport uio fixes to 4.14, to fix use-after-free memory errors.

Changed __poll_t to unsigned int as the former not found in 4.14, and
resolved some patch context conflicts.

Hailong Liu (1):
  uio: fix wrong return value from uio_mmap()

Hamish Martin (2):
  uio: Reduce return paths from uio_write()
  uio: Prevent device destruction while fds are open

Xiubo Li (5):
  uio: use request_threaded_irq instead
  uio: change to use the mutex lock instead of the spin lock
  uio: fix crash after the device is unregistered
  uio: fix possible circular locking dependency
  Revert "uio: use request_threaded_irq instead"
