- 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")
