Subject: [Intel-gfx] [PATCH v2 4/7] drm/i915: Fix wrongly populated plane possible_crtcs bit mask
Date: Tue, 11 Feb 2020 22:55:29 +0530 [thread overview]
Message-ID: <20200211172532.14287-5-anshuman.gupta@intel.com> (raw)
In-Reply-To: <20200211172532.14287-1-anshuman.gupta@intel.com>
As a disabled pipe in pipe_mask is not having a valid intel crtc,
driver wrongly populates the possible_crtcs mask while initializing
the plane for a CRTC. Fixing up the plane possible_crtcs mask.
changes since RFC:
- Simplify the possible_crtcs initialization. [Ville]
v2:
- Removed the unnecessary stack garbage possible_crtcs to
drm_universal_plane_init. [Ville]
