[PATCH 0/2] ASoC: NXP/Freescale: sort the reg_defaults tables

[Peter Ujfalusi <peter.ujfalusi@linux.intel.com>]

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.

The series is based on broonie/for-linus (05eebef3c7b2).

Affected tables:
  sgtl5000_reg_defaults    1 of 35 entries unreachable
  fsl_easrc_reg_defaults   3 of 120 entries unreachable
