Subject: [PATCH 2/2] net/phy/mdio-mscc-miim: Move the setting of mii_bus
 structure members in mscc_miim_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 20 Sep 2019 20:42:42 +0200

Move the modification of some members in the data structure “mii_bus”
for the local variable “bus” directly before the call of
the function “of_mdiobus_register” so that this change will be performed
only after previous resource allocations succeeded.
