The benet driver copies both fw_ver (32 bytes) and fw_on_flash (32 bytes)

Store fw_on_flash in ethtool_drvinfo->erom_version instead, which some
drivers use to report secondary firmware information.

You are changing user-visible behavior to silence a W=1 warning.
I can't stress enough how bad of an idea this is.
Please find a better fix.. or leave this code be.
