Subject[PATCH 4.9 056/172] net: phy: fix sign type error in genphy_config_eee_advert
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: jbrunet <jbrunet@baylibre.com>


[ Upstream commit 3bb9ab63276696988d8224f52db20e87194deb4b ]

In genphy_config_eee_advert, the return value of phy_read_mmd_indirect is
checked to know if the register could be accessed but the result is
assigned to a 'u32'.
Changing to 'int' to correctly get errors from phy_read_mmd_indirect.

Fixes: d853d145ea3e ("net: phy: add an option to disable EEE advertisement")
