6.18-stable review patch. If anyone has any objections, please let me know. ------------------ From: Peter Ujfalusi commit 2a8e4b7114f6493314348bda7e3d2141d218ef61 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"). The 0xdd93 and 0xdd94 entries are listed after 0xddc8 in rt1318_reg[], which leaves them unreachable for the binary search. 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.
