Subject: [v2 net 10/19] net/mlx5e: Fix wrong return value on ioctl EEPROM query failure

From: Gal Pressman <gal@...dia.com>

The ioctl EEPROM query wrongly returns success on read failures, fix
that by returning the appropriate error code.

Fixes: bb64143eee8c ("net/mlx5e: Add ethtool support for dump module EEPROM")
