Subject: usb: ehci-orion: fix probe for !GENERIC_PHY
From: Jonas Gorski <[email protected]>
commit db1319e166c5e872c4be54eac4e47454133708cf upstream.
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.
