Subject: patch "usb: gadget: udc: renesas_usb3: fix number of the pipes" added to usb-linus
Date: Thu, 30 Nov 2017 16:42:00 +0000 [thread overview]
Message-ID: <151206012034129@kroah.com> (raw)
This is a note to let you know that I've just added the patch titled
usb: gadget: udc: renesas_usb3: fix number of the pipes
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: gadget: udc: renesas_usb3: fix number of the pipes
This controller on R-Car Gen3 has 6 pipes that included PIPE 0 for
control actually. But, the datasheet has error in writing as it has
31 pipes. (However, the previous code defined 30 pipes wrongly...)
Anyway, this patch fixes it.
