Okay, I have reverted first the "spi: Fix spi device unregister flow"
to be sure I can reproduce the lockdep warning, indeed, it's there.

After applying the above mentioned patch it's gone.

On top I applied this ("spi: Don't have controller clean up spi device
before driver unbind") patch to see if there is any changes,
nope, seems everything is fine.

FWIW,
