Hmm...
rsnd_write/read() care about it (block/non-block),
and caller don't care it, is nice point of this function...

For example, SSI device have many ports (0-8),
but ADG is only 1 device.
On this driver, all devices are using rsnd_write/read() to
access register.

I can re-check it, but it will be next week
Thank you

Best regards
