From b9b092319be29bf665f1b004679de722b81c9123 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 18 May 2016 23:24:06 +0200 Subject: [PATCH] usb: phy: move msm_hsusb.h into driver As a preparation for another cleanup, this moves the header file for the phy-msm-usb driver into the driver itself. No other file includes it any more, and we don't really want it in the global namespace anyway.
