This is a note to let you know that I've just added the patch titled
usb: xhci-mtk: fix leakage of shared hcd when fail to set wakeup irq
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-next 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 also be merged in the next major kernel release during the merge window.
If you have any questions about this process, please let me know.

Can not set the @shared_hcd to NULL before decrease the usage count by usb_put_hcd(), this will cause the shared hcd not released.
