Hi everyone,

I've been playing around a bit with the FastRPC ioctl interface on the
Pixel 3a with some device tree patches. Since the ADSP crashes every 10
seconds, the inconvenience caused by related bugs encouraged me to write
a few fixes. A demonstration is provided in patch 2.

Please enjoy and review these patches for better userspace while remote
processors crash.

  misc: fastrpc: return -EPIPE to invocations on device removal
  misc: fastrpc: reject new invocations during device removal
