Subject: [PATCH] usbcore: don't log on consecutive debounce failures of the
 same port

commit 5ee0f803cc3a0738a63288e4a2f453c85889fbda upstream.

Some laptops have an internal port for a BT device which picks
up noise when the kill switch is used, but not enough to trigger
printk_rlimit(). So we shouldn't log consecutive faults of this kind.
