Shay Drory d7d7512496 devlink: Fix devlink parallel commands processing ... Commit 870c7ad4a5 ("devlink: protect devlink->dev by the instance lock") added devlink instance locking inside a loop that iterates over all the registered devlink instances on the machine in the pre-doit phase. This can lead to serialization of devlink commands over different devlink instances. For example: While the first devlink instance is executing firmware flash, all commands to other devlink instances on the machine are forced to wait until the first devlink finishes. Therefore, in the pre-doit phase, take the devlink instance lock only for the devlink instance the command is targeting. Devlink layer is taking a reference on the devlink instance, ensuring the devlink->dev pointer is valid. This reference taking was introduced by commit a380687200 ("devlink: take device reference for devlink object"). Without this commit, it would not be safe to access devlink->dev lockless.
