To simplify things, allow passing possible_crtcs as a parameter to drm_writeback_connector_init() and make changes to the other drm drivers to make them compatible with this change. changes in v2: - split the changes according to their functionality changes in v3: - allow passing possible_crtcs for existing users of drm_writeback_connector_init() - squash the vendor changes into the same commit so that each patch in the series can compile individually changes in v4: - keep only changes related to possible_crtcs - add line breaks after ARRAY_SIZE - stop using temporary variables for possible_crtcs changes in v5: - None changes in v6: - None changes in v7: - wrap long lines to match the coding style of existing drivers - Fix indentation and remove parenthesis where not needed - use u32 instead of uint32_t for possible_crtcs Signed-off-by: Abhinav Kumar Acked-by: Liviu Dudau Reviewed-by: Dmitry Baryshkov Reviewed-by: Laurent Pinchart --- drivers/gpu/drm/arm/display/komeda/komeda_wb_connector.c | 4 ++-- drivers/gpu/drm/arm/malidp_mw.c | 4 ++-- drivers/gpu/drm/drm_writeback.c | 7 ++++++- drivers/gpu/drm/rcar-du/rcar_du_writeback.c | 4 ++-- drivers/gpu/drm/vc4/vc4_txp.c | 3 ++- drivers/gpu/drm/vkms/vkms_writeback.c | 4 ++-- include/drm/drm_writeback.h | 3 ++- 7 files changed, 18 insertions(+), 11 deletions(-) diff --git a/drivers/gpu/drm/arm/display/komeda/komeda_wb_connector.c b/drivers/gpu/drm/arm/display/komeda/komeda_wb_connector.c index e465cc4..ce4b760 100644 --- a/drivers/gpu/drm/arm/display/komeda/komeda_wb_connector.c +++ b/drivers/gpu/drm/arm/display/komeda/komeda_wb_connector.c @@ -155,7 +155,6 @@ static int komeda_wb_connector_add(struct komeda_kms_dev *kms, kwb_conn->wb_layer = kcrtc->master->wb_layer;
