patch "usb: xhci: tegra:Fix PM usage reference leak of" added to usb-linus

This is a note to let you know that I've just added the patch titled

usb: xhci: tegra:Fix PM usage reference leak of

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: xhci: tegra:Fix PM usage reference leak of
tegra_xusb_unpowergate_partitions

pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in reference leak here. We fix it by replacing it with pm_runtime_resume_and_get to keep usage counter balanced.
