We can get down to this return value from ERR_CAST() without initializing hw. Set it to -ENOMEM so that we always return something sane. Fixes the following smatch warning: drivers/clk/rockchip/clk-half-divider.c:228 rockchip_clk_register_halfdiv() error: uninitialized symbol 'hw'. drivers/clk/rockchip/clk-half-divider.c:228 rockchip_clk_register_halfdiv() warn: passing zero to 'ERR_CAST' Cc: Elaine Zhang <[email protected]> Cc: Heiko Stuebner <[email protected]> Fixes: 956060a52795 ("clk: rockchip: add support for half divider") Reviewed-by: Heiko Stuebner <[email protected]> Signed-off-by: Stephen Boyd <[email protected]> Signed-off-by: Sasha Levin <[email protected]> --- drivers/clk/rockchip/clk-half-divider.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/clk/rockchip/clk-half-divider.c b/drivers/clk/rockchip/clk-half-divider.c index b333fc28c94b6..37c858d689e0d 100644 --- a/drivers/clk/rockchip/clk-half-divider.c +++ b/drivers/clk/rockchip/clk-half-divider.c @@ -166,7 +166,7 @@ struct clk *rockchip_clk_register_halfdiv(const char *name, unsigned long flags, spinlock_t *lock) { - struct clk *clk; + struct clk *clk = ERR_PTR(-ENOMEM); struct clk_mux *mux = NULL; struct clk_gate *gate = NULL; struct clk_divider *div = NULL; -- 2.25.1
