From 60b9f942bc059913bcdac90d5b225f557438b5c5 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Wed, 18 Apr 2018 11:26:19 +0200 Subject: USB: phy: drop unused legacy controller-phy bind helper Drop the unused legacy usb_bind_phy() helper whose last user was removed in 2016 when OMAP moved to device-tree boot (9080b8dc761a ("ARM: OMAP2+: Remove legacy usb-host.c platform init code")). Note that this means that for the last couple of years the phy_bind_list has been empty (when using mainline kernels) and that consequently all phy lookups using the usb_get_phy_dev() interface have failed with -ENODEV. This helper along with its current users will be removed by follow-on patches.
