Subject: [RFT PATCH v2 08/48] drm/panel: innolux-p079zca: Stop tracking prepared/enabled
Date: Fri,  3 May 2024 14:32:49 -0700	[thread overview]
Message-ID: <20240503143327.RFT.v2.8.I99c73621fe3fba067a5e7ee6a1f6293c23371e1e@changeid> (raw)
In-Reply-To: <20240503213441.177109-1-dianders@chromium.org>

As talked about in commit d2aacaf07395 ("drm/panel: Check for already
prepared/enabled in drm_panel"), we want to remove needless code from
panel drivers that was storing and double-checking the
prepared/enabled state. Even if someone was relying on the
double-check before, that double-check is now in the core and not
needed in individual drivers.

Changes in v2:
- Only handle 1 panel per patch.
- Split removal of prepared/enabled from handling of remove/shutdown.
