Subject: drm/i915: Remove redundant check on execlists interrupt
Git-commit: 8e47b4b65bbd646b4d8be28e1ffff7a684f60fe6
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Since commit 4a118ecbe99c ("drm/i915: Filter out spurious execlists
context-switch interrupts") we probe execlists->active, and no longer
have to peek at the execlist interrupt to determine if the tasklet still
needs to be run to drain the ELSP.
