Ok I applied this one to clk-next.And I squashed this in to silence the following checker warning. drivers/clk/sunxi/clk-sun4i-display.c:110:33: warning: Variable length array is used. ---8<---diff --git a/drivers/clk/sunxi/clk-sun4i-display.cb/drivers/clk/sunxi/clk-sun4i-display.c index f02e250e64ed..f8ff6c4a5633 100644--- a/drivers/clk/sunxi/clk-sun4i-display.c +++ b/drivers/clk/sunxi/clk-sun4i-display.c@@ -107,7 +107,7 @@ static intsun4i_a10_display_reset_xlate(struct reset_controller_dev *rcdev, ?static void __init sun4i_a10_display_init(struct device_node *node, ? ??const struct sun4i_a10_display_clk_data *data) ?{ - const char *parents[data->parents]; + const char *parents[4];This change breaks at least de_[bf]e clocks which have 3 clock parents.quoted
I just used the largest data->parents number, which was 4. How does that break anything?If you look at the?sun4i_a10_display_init, it contains this block: ? ? ret = of_clk_parent_fill(node, parents, ARRAY_SIZE(parents)); ????if (ret != ARRAY_SIZE(parents)) { ????????pr_err("%s: Could not retrieve the parents\n", clk_name); ????????goto unmap; ????} of_clk_parent_fill returns 3 for de_be/de_fe nodes, and ARRAY_SIZE(parents) is 4.
Replacing both ARRAY_SIZE(parents) by data->parents would work though.
