From fcb9bba47fb5ff39912f8f3b7b6d32992e461368 Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Tue, 15 Oct 2019 09:11:31 -0700 Subject: [PATCH] drm/i915/ehl: Don't forget to set TC long detect function Since EHL's MCC PCH reuses one of the TC pins we need to supply a TC long detect function when handling the interrupts.
