The function has an unsigned return type, but returns a negative constant to indicate an error condition. The result of calling the function is always stored in a variable of type (signed) int, and thus unsigned can be dropped from the return type. A sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @exists@ identifier f; constant C; @@ unsigned f(...) { <+... * return -C; ...+> } // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/atm/firestream.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/atm/firestream.c b/drivers/atm/firestream.c index 8717809..1af977e 100644 --- a/drivers/atm/firestream.c +++ b/drivers/atm/firestream.c @@ -444,8 +444,8 @@ static inline void fs_kfree_skb (struct sk_buff * skb) #define ROUND_NEAREST 3 /********** make rate (not quite as much fun as Horizon) **********/ -static unsigned int make_rate (unsigned int rate, int r, - u16 * bits, unsigned int * actual) +static int make_rate(unsigned int rate, int r, + u16 *bits, unsigned int *actual) { unsigned char exp = -1; /* hush gcc */ unsigned int man = -1; /* hush gcc */ -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
