X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=20fae983c6667d038e810c618e3340946b8dc506;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git drm/i915: Update atomic state when removing mst connector, v3. Fully remove the MST connector from the atomic state, and remove the early returns in check_*_state for MST connectors. With atomic the state can be made consistent all the time. Thanks to Sivakumar Thulasimani for the idea of using drm_atomic_helper_set_config. Changes since v1: - Remove the MST check in intel_connector_check_state too. Changes since v2: - Use drm_atomic_helper_set_config.
