Subject: iwlwifi: add device / firmware to fw-error-dump file
Content-Transfer-Encoding: 8bit
Origin: https://git.kernel.org/linus/06ddbf5adac1fd2a031eade8a92239abfa6db93a
Bug-Debian: https://bugs.debian.org/767088
This can be useful later for parsing since the parsing may
differ based on the device's family / bus.
Also add the human readable version of the firmware.
