mvebu: kirkwood: fix ehci-orion probe if generic-phy isn't enabled
Properly treat -ENOSYS as no PHY, else ehci-orion won't work without generic phy support. Signed-off-by: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 46711

+Subject: [PATCH] usb: ehci-orion: fix probe for !GENERIC_PHY
+
+Commit d445913ce0ab7f ("usb: ehci-orion: add optional PHY support")
+added support for optional phys, but devm_phy_optional_get returns
+-ENOSYS if GENERIC_PHY is not enabled.
+
+This causes probe failures, even when there are no phys specified:
+
+[ 1.443365] orion-ehci f1058000.usb: init f1058000.usb fail, -38
+[ 1.449403] orion-ehci: probe of f1058000.usb failed with error -38
+
+Similar to dwc3, treat -ENOSYS as no phy.
+
+Fixes: d445913ce0ab7f ("usb: ehci-orion: add optional PHY support")
