[PATCH v3 00/10] i2c: core: adapter registration fixes

[Johan Hovold]

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.

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()
