From: Ravi Bangoria <[email protected]> [ Upstream commit f0a30dca5f84fe8048271799b56677ac2279de66 ]
'*ntevs' contains number of elements present in 'tevs' array. If there are no elements in array, 'tevs2' can be directly assigned to 'tevs' without allocating more space. So the condition should be '*ntevs == 0' not 'ntevs == 0'.
