From 196cabd4a39496038ee81c2755496955e7355bd5 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Thu, 20 Aug 2015 10:47:38 +0300 Subject: [PATCH] drm/i915: add MISSING_CASE annotation to ibx_digital_port_connected With the case added for eDP on port A (always connected from this function's point of view), we should not be hitting any of the default cases in ibx_digital_port_connected, so add MISSING_CASE annotation.
