X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9b5edbf7a462b7c846e9d4675b9b72b7a4e84de9;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git drm/atomic: Clear crtc_state->active in drm_atomic_helper_set_config. This fixes some regressions in i915 when converting to atomic. set_config failed with -EINVAL, and I received the following warning in dmesg: [drm:drm_atomic_crtc_check] [CRTC:20] active without enabled Solve this by clearing active when a crtc is disabled. Because crtc_state->enable implies that connectors are active the change from disabled->enabled can only happen for the crtc that's being set_config'd, and checking for !crtc_state->enable is sufficient here.
