7.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Peter Ujfalusi <[email protected]> commit d74aac116cfb2058b15df53996d23232b310f7ff 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"). cs35l41_reg[] lists CS35L41_BSTCVRT_PEAK_CUR (0x3808) after CS35L41_BSTCVRT_COEFF (0x3810) and CS35L41_BSTCVRT_SLOPE_LBST (0x3814), so the binary search does not find those two entries. regcache_reg_needs_sync() then cannot compare them 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.
