Subject: [Intel-gfx] [CI] drm/i915: split intel_modeset_init() to pre/post irq install
Date: Mon, 24 Feb 2020 14:08:28 +0200	[thread overview]
Message-ID: <20200224120828.22105-1-jani.nikula@intel.com> (raw)

Split inte_modeset_init() to parts before and after irq install, to
facilitate further cleanup. The error paths are a mess, otherwise no
functional changes.
