So may be we can do this:

diff --git a/drivers/net/wireless/ray_cs.c b/drivers/net/wireless/ray_cs.c
index c1d542bfa530..9ea695459342 100644
--- a/drivers/net/wireless/ray_cs.c
+++ b/drivers/net/wireless/ray_cs.c
@@ -2794,8 +2794,7 @@ static int __init init_ray_cs(void)
        proc_create_data("driver/ray_cs/translate", 0200, NULL, 
&int_proc_ops,
                         &translate);
 #endif
-       if (translate != 0)
-               translate = 1;
+       translate == !!translate;
        return 0;
 } /* init_ray_cs */
