Move the declaration to a header to fix W=1 build warning: drivers/clk/samsung/clk-s3c64xx.c:391:13: warning: no previous prototype for 's3c64xx_clk_init' [-Wmissing-prototypes] 391 | void __init s3c64xx_clk_init(struct device_node *np, unsigned long xtal_f, Signed-off-by: Krzysztof Kozlowski Reviewed-by: Tomasz Figa Acked-by: Chanwoo Choi Reviewed-by: Stephen Boyd --- Changes since v1: 1. Drop __init from header (as suggested by Stephen), 2. Add necessary header and forward declaration (as suggested by Stephen), 3.
