  "message": "regmap: sdw-mbq: don\u0027t call an unset readable_reg callback\n\nregmap_sdw_mbq_poll_busy() decides whether to poll the Function Busy bit\nby calling ctx-\u003ereadable_reg(), which is a straight copy of\nconfig-\u003ereadable_reg. That callback is optional: regmap_readable() treats\na NULL -\u003ereadable_reg as \"every register is readable\", and drivers rely on\nthat. es9356 and tac5xx2-sdw both build an MBQ regmap without one.\n\nSince commit ca1b11b36d82 (\"regmap: sdw-mbq: Allow defers on undeferrable\ncontrols\") the poll runs on every -ENODATA, not only for Controls the\ndriver marked deferrable, so any of those devices answering\nCOMMAND_IGNORED takes the kernel through a NULL function pointer.\n\nTreat a missing callback the way the rest of regmap does and poll.\n\nFixes: 5bc493bf0c37 (\"regmap: sdw-mbq: Add support for SDCA deferred controls\")\nSigned-off-by: Andrey Golovko \u003candrey.golovko@gmail.com\u003e\nReviewed-by: Charles Keepax \u003cckeepax@opensource.cirrus.com\u003e\nLink: https://patch.msgid.link/20260811184500.5312-1-andrey.golovko@gmail.com\nSigned-off-by: Mark Brown \u003cbroonie@kernel.org\u003e\n",
