Subject: [PATCH 13/15] ath6kl: use new module_firmware_crashed()
Date: Sat,  9 May 2020 04:35:50 +0000
Message-ID: <20200509043552.8745-14-mcgrof@kernel.org> (raw)
In-Reply-To: <20200509043552.8745-1-mcgrof@kernel.org>

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.
