[PATCH v2 01/11] usb: musb: add musb->id to identify core instance
From: Ajay Kumar Gupta <hidden>
Date: 2012-07-17 09:13:17
Also in:
linux-omap
Subsystem:
musb multipoint high speed dual-role controller, omap usb support, the rest, usb subsystem · Maintainers:
Bin Liu, Linus Torvalds, Greg Kroah-Hartman
Added 'id' field within 'struct musb' which can be used to determine the current instance of musb controller. Also defined musb_ida in musb_core.c to manage the core ids.
