[PATCH v2 09/15] qed: use new module_firmware_crashed()

From: Luis Chamberlain <mcgrof@kernel.org>
Date: 2020-05-15 21:30:06
Also in: lkml
Subsystem: networking drivers, qlogic ql4xxx ethernet driver, the rest · Maintainers: Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

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.
