This is a note to let you know that I've just added the patch titled
USB: ehci-tegra: remove redundant gpio_set_value
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 will 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: ehci-tegra: remove redundant gpio_set_value
The immediately preceding gpio_direction_output() already set the value,
so there's no need to repeat it. This also prevents gpio_set_value() from
WARNing when the GPIO is sleepable (e.g. is on an I2C expander); the set
direction API is always sleepable, but plain set_value isn't.
