Subject: net: phy: micrel: Pass .probe for KS8737
From: Fabio Estevam <festevam@xxxxxxx>
commit 15f03ffe4bb951e982457f44b6cf6b06ef4cbb93 upstream.
Since commit f1131b9c23fb ("net: phy: micrel: use
kszphy_suspend()/kszphy_resume for irq aware devices") the kszphy_suspend/
resume hooks are used.
These functions require the probe function to be called so that
priv can be allocated.
Otherwise, a NULL pointer dereference happens inside
kszphy_config_reset().
