[PATCH 13/15] ath6kl: use new module_firmware_crashed()

From: Luis Chamberlain <mcgrof@kernel.org>
Date: 2020-05-09 04:36:45
Also in: linux-wireless, lkml
Subsystem: atheros ath generic utilities, atheros ath6kl wireless driver, the rest · Maintainers: Jeff Johnson, Linus Torvalds

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.
