Title
vdpa/mlx5: Fix invalid mr resource destroy
Summary
In the Linux kernel, the following vulnerability has been resolved: vdpa/mlx5: Fix invalid mr resource destroy Certain error paths from mlx5_vdpa_dev_add() can end up releasing mr resources which never got initialized in the first place. This patch adds the missing check in mlx5_vdpa_destroy_mr_resources() to block releasing non-initialized mr resources. Reference trace: mlx5_core 0000:08:00.2: mlx5_vdpa_dev_add:3274:(pid 2700) warning: No mac address provisioned?
