If "pool_id" is negative then it leads to a read before the start of the array. If "cli_id" is out of bounds then it leads to a NULL dereference of "cli". GCC would have warned about that bug except that we initialized the warning message away. Also it's better to put the parameter names into the function declaration in the .h file. It serves as a kind of documentation. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
