ionic: catch failure from devlink_alloc
CVE-2023-53470
Description
In the Linux kernel, the following vulnerability has been resolved:
ionic: catch failure from devlink_alloc
Add a check for NULL on the alloc return. If devlink_alloc() fails and we try to use devlink_priv() on the NULL return, the kernel gets very unhappy and panics. With this fix, the driver load will still fail, but at least it won't panic the kernel.
