Subject: [PATCH 3.18 06/22] usb: ehci-orion: fix probe for !GENERIC_PHY
Date: Thu, 13 Jul 2017 17:42:46 +0200 [thread overview]
Message-ID: <20170713153934.394177946@linuxfoundation.org> (raw)
In-Reply-To: <20170713153934.089183081@linuxfoundation.org>
3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jonas Gorski <jogo@openwrt.org>
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.
Fixes: d445913ce0ab7f ("usb: ehci-orion: add optional PHY support")
