[PATCH 1/3] e1000: mtd: remove needless error checking for device parameter

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The invm device is specifically created for the EEPROM, so adding a
parameter should not result in a name clash.

This leaves only -ENOMEM as possible error. As the driver is usable
without EEPROM being writable, don't propagate the error.
