[PATCH 1/6] usb: dwc2/gadget: move phy bus legth initialization

From: Robert Baldyga
Date: Tue Sep 09 2014 - 04:47:47 EST


From: Kamil Debski <k.debski@xxxxxxxxxxx>

This patch moves the part of code that initializes the PHY bus width.
This results in simpler code and removes the need to check whether
the Generic PHY Framework is used.
