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.
|
|
|
|
