patch "usb: host: xhci: fix ep context print mismatch in debugfs" added to usb-linus
Subsystems (3)
This is a note to let you know that I've just added the patch titled
usb: host: xhci: fix ep context print mismatch in debugfs
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: usb: host: xhci: fix ep context print mismatch in debugfs
dci is 0 based and xhci_get_ep_ctx() will do ep index increment to get the ep context.
