In some cases, we need regmap's format parse_val function
to do be/le translation according to the bus configuration.
For example, snd_soc_bytes_put() uses regmap to write/read values,
and use cpu_to_be() directly to covert MASK into big endian. This
is a defect, and should use regmap's format function to do it according
to bus configuration.

I can't do anything useful with patches that are quoted, sorry. None of

Hi ,Mark
Sorry for giving you trouble. I also don't know how to remove
the quotes. So i just submit the patches again. Thanks!

Hi, Mark:
Do you still have any other problem which have impact on evaluating
these two patches?

You're chasing me for a reply after a day - that's way too soon, please
allow a reasonable time for a response. A week or so is usually a good
minimum.

Hi, Mark:
My intention is not chasing you. I am just afraid if there is any
other mistake when submitting this patch to open source. Please do what
you want to do. Thanks!

Applied, thanks. Please use subject lines matching the style for the
subsystem.
