net: dsa: bcm_sf2: Fix a possible memory leak in bcm_sf2_mdio_register()
bcm_sf2_mdio_register() calls of_phy_find_device() and then
phy_device_remove() in a loop to remove existing PHY devices.
of_phy_find_device() eventually calls bus_find_device(), which calls
get_device() on the returned struct device * to increment the refcount.
The current implementation does not decrement the refcount, which causes
memory leak.
This commit adds the missing phy_device_free() call to decrement the
refcount via put_device() to balance the refcount.
