Subject: [PATCH 3/3] thunderbolt: Mask ring interrupt properly when polling starts
Date: Fri,  1 Dec 2017 15:08:05 +0300	[thread overview]
Message-ID: <20171201120805.60852-4-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20171201120805.60852-1-mika.westerberg@linux.intel.com>

When ring enters polling mode we are expected to mask the ring interrupt
before the callback is called. However, the current code actually
unmasks it probably because of a copy-paste mistake.

Mask the interrupt properly from now on.

Fixes: 4ffe722eefcb ("thunderbolt: Add polling mode for rings")
