drivers/isdn/sc/ioctl.c: add missing kfree
spid has been allocated in this function and so should be freed before leaving it, as in the other error handling cases. The semantic match that finds the problem is as follows: (http://www.emn.fr/x-info/coccinelle/) @r exists@ expression E,E1; statement S; position p1,p2,p3; @@ E =@p1 \(kmalloc\|kcalloc\|kzalloc\)(...) ... when != E = E1 if (E == NULL || ...)
