Merge branch 'devlink_register-last' 

Leon Romanovsky says:

====================
Move devlink_register to be last devlink command

This is second version of patch series
https://lore.kernel.org/netdev/cover.1628599239.git.leonro@nvidia.com/

The main change is addition of delayed notification logic that will
allowed us to delete devlink_params_publish API (future series will
remove it completely) and conversion of all drivers to have devlink_register
being last commend.

The series itself is pretty straightforward, except liquidio driver
which performs initializations in various workqueues without proper
locks. That driver doesn't hole device_lock and it is clearly broken
for any parallel driver core flows (modprobe + devlink + PCI reset will
100% crash it).

In order to annotate devlink_register() will lockdep of holding
device_lock, I added workaround in this driver.

Thanks

----------------------
From previous cover letter:
Hi Dave and Jakub,

This series prepares code to remove devlink_reload_enable/_disable API
and in order to do, we move all devlink_register() calls to be right
before devlink_reload_enable().

The best place for such a call should be right before exiting from
the probe().

This is done because devlink_register() opens devlink netlink to the
users and gives them a venue to issue commands before initialization
is finished.

1. Some drivers were aware of such "functionality" and tried to protect
themselves with extra locks, state machines and devlink_reload_enable().
Let's assume that it worked for them, but I'm personally skeptical about
it.

2. Some drivers copied that pattern, but without locks and state
machines. That protected them from reload flows, but not from any _set_
routines.

3. And all other drivers simply didn't understand the implications of early
devlink_register() and can be seen as "broken".
