From b084662776be8b07ab9114ff1a16a4e9bf907d35 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Thu, 19 Nov 2015 12:15:43 -0600 Subject: [PATCH] usb: dwc3: remove dwc3-qcom in favor of dwc3-of-simple Now that we have a generic dwc3-of-simple.c, we can use that instead of maintaining dwc3-qcom.c which is extremely similar.
