Hi everyone,

I've been playing around a bit with the FastRPC ioctl interface on the
Pixel 3a with some device tree patches. I was testing on a device tree
that caused the ADSP to crash every 10 seconds, and 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.
