From: Jonas Gorski Date: Sun, 23 Aug 2015 13:01:08 +0000 (+0200) Subject: usb: ehci-orion: fix probe for !GENERIC_PHY X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=db1319e166c5e872c4be54eac4e47454133708cf;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git 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.
