Takashi Iwai 4ceba98d3f regmap: Skip read-only registers in regcache_sync() ...

regcache_sync() spews warnings when a value was cached for a read-only
register as it tries to write all registers no matter whether they are
writable or not.  This patch adds regmap_wrtieable() checks for
avoiding it in regcache_sync_block_single() and regcache_block_raw().
