Subject: [PATCH v2 04/15] bnxt: use new module_firmware_crashed()
Date:   Fri, 15 May 2020 21:28:35 +0000

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.
