Subject: [Intel-gfx] [PATCH 1/3] drm/i915/display: Move dc3co_exitline variable to struct intel_psr
Date: Wed,  3 Mar 2021 18:41:59 +0200	[thread overview]
Message-ID: <20210303164201.31301-1-gwan-gyeong.mun@intel.com> (raw)

dc3co_exitline is indirectly called by intel_psr_compute_config().
And it will not be changed until the next calling of
intel_psr_compute_config(). So in order to use dc3co_exitline without
intel_crtc_state on other psr internal function, it moves dc3co_exitline
variable to struct intel_psr.
And it removes a dc3co_enabled variable from struct intel_psr.
