UASP: updates and merges
From: Luben Tuikov
Date: Wed Mar 02 2011 - 14:11:54 EST
I've merged the latest master (dd9c154). The UASP driver saw the following update:
[USB] UASP: Unlock device after reset; EP updates
* Unlock the device after reset.
* Initialize urb->ep directly. struct
uasp_tport_info already records the struct
usb_host_endpoint which makes it easy to
directly initialize urb->ep. This anticipates
when drivers would have to initialize the ep in
the urb directly as opposed to the USB core
having to use pipes.
* Use the UAS pipe macros throughout the code for
endpoint indexes.
The branch can be found here off of master:
