Subject: [PATCH 08/15] ehea: use new module_firmware_crashed()
Date: Sat, 9 May 2020 04:35:45 +0000 [thread overview]
Message-ID: <20200509043552.8745-9-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.
