This series fixes a number of bugs related to adapter registration found
through inspection (when looking into addressing i2c lifetime issues).

Included are also two related cleanups.

Johan


Changes in v3:
 - split NULL-deref fix from probe loop fix (2-3/10)
 - add missing adapter name error handling (5/10)
 - replace adapter in IDR also on registration failures (8/10)

Changes in v2:
 - fix irq domain leak (new, flagged by Sashiko when reviewing v1)
 - add adapter to IDR before registration as needed by i2c-dev
 - honour devicetree alias also when using i2c_add_numbered_adapter()

I intend to review the series. I wonder if it makes sense to wait until
you don't see any valuable input from Sashiko anymore. Otherwise a
reworked series X+1 will be sent while I am still looking at series X.

You can always wait a few hours until the Sashiko output is available if
you're worried about that, but I don't expect there to be any further
revisions of this series.
