Subject: [PATCH 2.6.7] usb gadgetfs, handle omap_udc
Date: Sun, 11 Jul 2004 13:37:21 -0700
From: David Brownell <[EMAIL PROTECTED]>
To: Greg KH <[EMAIL PROTECTED]>,  [EMAIL PROTECTED]

Adds a new UDC, and also some sparse annotations.

Please merge.

- Dave

p.s. Note:  the patch to change kiocb.private to
       a pointer will break the current gadgetfs on
       some platforms; separate patch forthcoming.
       (That's why when changing a member type, it's
       best to change its name too.)

Tell gadgetfs about omap_udc.
Add some missing __user annotations.
