[PATCH v3 03/12] usb: dwc2/gadget: move phy bus legth initialization

[Robert Baldyga]

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.
