But the phy needed on px30, also has the capability to probe after the lvds. So make the rest of the lvds probe/bind logic also use more modern logging than DRM_DEV_ERR, that is deprecated anyway. changes in v2: - reword the messages about getting (and preparing) pclk (Quentin) - use a ret = dev_err_probe(dev, -EINVAL, ...) pattern in some (additional) places (Quentin) Heiko Stuebner (2): drm/rockchip: lvds: move pclk preparation in with clk_get drm/rockchip: lvds: Hide scary error messages on probe deferral drivers/gpu/drm/rockchip/rockchip_lvds.c | 78 +++++++++--------------- 1 file changed, 28 insertions(+), 50 deletions(-)
