Subject: usb: xhci-mtk: fix leakage of shared hcd when fail to set wakeup irq
From: Chunfeng Yun <chunfeng.yun@xxxxxxxxxxxx>
commit 03a88b0bafbe3f548729d970d8366f48718c9b19 upstream.
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.
