[dpdk-dev] [PATCH v6 9/9] common/mlx5: remove class checks from individual driver

[Parav Pandit <parav@mellanox.com>]

Now that mlx5_pci bus does the check for enabled classes and performs
probe(), remove() of associated classes, individual class driver
does not need to check if other driver is enabled.
