Subject: [PATCH net v2 2/2] net: phy: micrel: Pass .probe for KS8737

From: Fabio Estevam <festevam@...x.de>

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().
