ASoC: codec drivers: sort the reg_defaults tables
Peter Ujfalusi <peter.ujfalusi@linux.intel.com> says: reg_defaults must be sorted by ascending register address, since regcache_lookup_reg() locates entries in it with bsearch(). When a table is not sorted, bsearch() cannot find the entries which follow a descending step, so regcache_reg_needs_sync() falls back to reporting that a sync is needed for them. Those registers are then written to the device on every regcache_sync() even when they were never touched. See commit fd80df352ba1 ("regcache: Add support for sorting defaults arrays") for the same problem in a different context. Affected tables: ml26124_reg 1 of 79 entries unreachable cx2072x_reg_defaults 75 of 132 entries unreachable max9860_reg_defaults 1 of 14 entries unreachable stih407_sas_reg_defaults 1 of 2 entries unreachable Link: https://patch.msgid.link/20260805122811.13713-1-peter.ujfalusi@linux.intel.com
