i2c/i2c-pasemi.c: Fix unsigned return type
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@diku.dk> Acked-by: Olof Johansson <olof@lixom.net> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
