Subject: [PATCH 14/15] brcm80211: use new module_firmware_crashed()

From: Luis Chamberlain <[email-masked]>
Date: Sat, 9 May 2020 04:35:51 +0000

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.
