eth: mlx4: Fix IS_ERR() vs NULL check bug in mlx4_en_create_rx_ring
Summary
In the Linux kernel, the following vulnerability has been resolved:
eth: mlx4: Fix IS_ERR() vs NULL check bug in mlx4_en_create_rx_ring
Replace NULL check with IS_ERR() check after calling page_pool_create()
since this function returns error pointers (ERR_PTR).
Using NULL check could lead to invalid pointer dereference.
