kfifo: fix kfifo_alloc() to return a signed int value
Add a new __kfifo_int_must_check_helper() helper function, which is needed for kfifo_alloc() to return the right signed integer value. The origin __kfifo_must_check_helper() helper was renamed into __kfifo_uint_must_check_helper() to show the sign which is expected and returned. (And revert the temporary disabling of __kfifo_must_check_helper()) Signed-off-by:Stefani Seibold <stefani@seibold.net> Acked-by:
