From: Rafał Miłecki <[email protected]> Firmware may report general errors using a special message type. Add basic support for it by simply decoding & printing an error number.
A sample situation in which firmware reports a buf error: CONSOLE: 027084.733 no host response IOCTL buffer available..so fail the request will now produce a "Firmware reported general error: 9" on the host.
