From e086558ae923adc71c9718140ee0f6ba9508ec30 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 26 Feb 2020 13:25:14 +0200 Subject: [PATCH] drm/omap: dss: Remove unused omap_dss_device operations The omap_dss_device .pre_enable(), .post_disable() and .set_timings() are not used anymore. Remove them.
