Yes, usually when the register cache is not used, the number of the

will add the defaults register values though the cache type is
REGCACHE_NONE for some reasons.
I can't find either of those in the kernel tree...
This could be found in the for-next branch of regmap tree.


This patch may be not the best, but will be a bit meaningful for some
drivers like drv2267.c/led_lp8860.c for now.
TBH if we're going to do something here it might be as well to print a
warning if something is providing register defaults but no cache.
Yes, Agreed.

I will enhance this later in another patch, just abandon this one please.
