Subject: [PATCH 14/15] brcm80211: use new module_firmware_crashed()
Date: Sat,  9 May 2020 04:35:51 +0000	[thread overview]
Message-ID: <20200509043552.8745-15-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.
