ASoC: max9860: sort the register default table

Browse source

reg_defaults must be sorted by ascending register address, as
regcache_lookup_reg() locates entries in it with bsearch().  See commit
fd80df352b ("regcache: Add support for sorting defaults arrays").

MAX9860_PWRMAN (0x10) is listed as the first entry, before
MAX9860_INTEN (0x02), which makes MAX9860_INTEN 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.
