Subject: [PATCH v3 6/8] bnxt_en: use new taint_firmware_crashed()
Date: Tue, 26 May 2020 14:58:13 +0000 [thread overview]
Message-ID: <20200526145815.6415-7-mcgrof@kernel.org> (raw)
In-Reply-To: <20200526145815.6415-1-mcgrof@kernel.org>
From: Vasundhara Volam <vasundhara-v.volam@broadcom•com>
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.
