6.18-stable review patch. If anyone has any objections, please let me know. ------------------ From: Peter Ujfalusi commit 8dd18d9956bfd74531bfd7088e59586e3e115789 upstream. 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"). PM4125_SWR_HPHPA_HD2 (0x3090) is listed before PM4125_ANA_HPHPA_SPARE_CTL (0x308e), which makes the latter unreachable. regcache_reg_needs_sync() then cannot compare it against its default and reports that a sync is needed, so it is written to the device on every regcache_sync() even when it was never touched. Sort the table by register address.
