From 42a58c9949ddf16e557f5c2e22566f3440e7b60f Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Mon, 13 Mar 2017 15:25:23 +0900 Subject: [PATCH] usb: host: ehci-platform: set hcd->phy to avoid phy_get() in usb_add_hcd() This patch sets hcd->phy from own phy context to avoid phy_get() in usb_add_hcd(). Since core/hcd.c manages the phy only in usb_add_hcd() and usb_remove_hcd(), there is difficult to manage the phy in suspend/resume.
