Introduce a connector state subclass and move the data from hdmi_data in there. Suggested-by: Maxime Ripard Signed-off-by: Alex Bee --- changes in v2: - new patch changes in v3: - added missing customizations of reset and atomic_destroy_state connector hooks - moved inno_conn_state member assignments to atomic_check changes in v4: - added missing state destroy in reset hook drivers/gpu/drm/rockchip/inno_hdmi.c | 117 ++++++++++++++++++++------- 1 file changed, 90 insertions(+), 27 deletions(-) diff --git a/drivers/gpu/drm/rockchip/inno_hdmi.c b/drivers/gpu/drm/rockchip/inno_hdmi.c index c306db90832a..e43fce968310 100644 --- a/drivers/gpu/drm/rockchip/inno_hdmi.c +++ b/drivers/gpu/drm/rockchip/inno_hdmi.c @@ -26,11 +26,6 @@ #include "inno_hdmi.h" -struct hdmi_data_info { - unsigned int enc_out_format;
