So the driver has to keep on assuming the first clock is the functional clock, and this patch is thus not needed nor desired. > if (IS_ERR(priv->clk)) { > error = PTR_ERR(priv->clk); > goto out_release; Gr{oetje,eeting}s, Geert

The bindings have been updated to support two clocks, but the original clock now requires the name fck to distinguish it from the other. Signed-off-by: Adam Ford <aford173@gmail.com> --- drivers/net/ethernet/renesas/ravb_main.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
