Subject: [PATCH] usb: Don't print a warning if interface driver rebind is deferred at resume
Date: Mon, 4 Dec 2017 14:05:45 +0200 [thread overview]
Message-ID: <1512389145-27213-1-git-send-email-mathias.nyman@linux.intel.com> (raw)
In-Reply-To: <20171118102835.GG8368@kroah.com>
Interface drivers like btusb that don't support reset-resume will be
rebound at resume if port was reset. Rebind is done during the pm_ops
.complete callback when probe returns EPROBE_DEFER as default.
Remove the "rebind failed: -517" message.
Device probe will eventually take place later.
