[PATCH 10/15] soc: qcom: ipa: use new module_firmware_crashed()

From: Luis Chamberlain
Date: Sat May 09 2020 - 00:36:53 EST


This makes use of the new module_firmware_crashed() to help
annotate when firmware for device drivers crash. When firmware
crashes devices can sometimes become unresponsive, and recovery
sometimes requires a driver unload / reload and in the worst cases
a reboot.

Using a taint flag allows us to annotate when this happens clearly.
