Subject: [PATCH v2 0/9] i2c: core: adapter registration fixes
Date: Fri, 8 May 2026 11:03:02 +0200 [thread overview]
Message-ID: <20260508090311.379333-1-johan@kernel.org> (raw)
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 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()
