Hi This series tightens the I3C core's handling of Hot-Join across system suspend, shutdown and unregister, consolidates the per-driver Hot-Join worker into the core, and finally wires the MIPI I3C HCI driver into the new Hot-Join framework. Note all patches have now been reviewed by Frank. It applies on top of: https://lore.kernel.org/linux-i3c/[email protected]/ which is also fully reviewed by Frank. Patches 1-2 fix latent races in the existing Hot-Join machinery (suspend vs. Hot-Join work, and concurrent sysfs writers). Patches 3-5 consolidate the per-driver Hot-Join worker into the core and add proper teardown via an i3c_bus_type shutdown callback. Patch 6 defers driver-model registration of newly discovered devices out of the DAA caller's context, so resume-time DAA does not push device probing into the controller's resume sequence. Patches 7-8 add Hot-Join support to MIPI I3C HCI.
