Subject: [PATCH] net: hns: fix LED configuration for marvell phy

driver inclusion
category: bugfix
bugzilla: NA
CVE: NA

Since commit(net: phy: marvell: change default m88e1510 LED configuration),
the active LED of Hip07 devices is always off, because Hip07 just
use 2 LEDs.
This patch adds a phy_register_fixup_for_uid() for m88e1510 to
current the LED configuration.
