From b9339ee3fccc79e751a2f7bde42c5dd57b38b2a9 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Wed, 5 Aug 2026 12:02:31 +0300 Subject: [PATCH] ASoC: rt712-sdca-dmic: sort the register default table reg_defaults must be sorted by ascending register address, as regcache_lookup_reg() locates entries in it with bsearch(). See commit fd80df352ba1 ("regcache: Add support for sorting defaults arrays"). rt712_sdca_dmic_reg_defaults[] is grouped by SDCA entity instead, so the binary search does not find 3 of its entries. regcache_reg_needs_sync() then cannot compare those against their default and reports that a sync is needed, so they are written to the device on every regcache_sync() even when they were never touched. Sort the table by register address.
