thunderbolt: Mask ring interrupt properly when polling starts

westeri · gregkh · commit 74657181e7c4 · 2017-12-16T16:37:51.000+01:00
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.
