Subject: [PATCH 4/4] ASoC: sti-sas: sort the register default table
Date: Wed,  5 Aug 2026 15:28:11 +0300	[thread overview]
Message-ID: <20260805122811.13713-5-peter.ujfalusi@linux.intel.com> (raw)
In-Reply-To: <20260805122811.13713-1-peter.ujfalusi@linux.intel.com>

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").

STIH407_AUDIO_DAC_CTRL (0xa8) is listed before
STIH407_AUDIO_GLUE_CTRL (0xa4), 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.
