Title
ixgbe: fix too early devlink_free() in ixgbe_remove()
Summary
In the Linux kernel, the following vulnerability has been resolved: ixgbe: fix too early devlink_free() in ixgbe_remove() Since ixgbe_adapter is embedded in devlink, calling devlink_free() prematurely in the ixgbe_remove() path can lead to UAF. Move devlink_free() to the end.
