Subject: [PATCH] drm/atomic: Clear crtc_state->active in drm_atomic_helper_set_config.
Date: Mon, 01 Jun 2015 08:59:53 +0200	[thread overview]
Message-ID: <556C02E9.6060704@linux.intel.com> (raw)

This fixes some regressions in i915 when converting to atomic.
set_config failed with -EINVAL, and I received the following warning
in dmesg:

[drm:drm_atomic_crtc_check] [CRTC:20] active without enabled

Solve this by clearing active when a crtc is disabled.

Because crtc_state->enable implies that connectors are active the
change from disabled->enabled can only happen for the crtc that's
being set_config'd, and checking for !crtc_state->enable is sufficient
here.
