Re: [PATCH v2 0/8] i2c mux cleanup and locking update

Hi Wolfram and Peter,
I will give my opinion about the path chosen although it should be
taken lightly.

I can see that hardware guys missed the software guys again on the
development path, but since this happens more often than not, I would
say it seems OK to have support for this as long as it does not make
more complex (longer) standard i2c transfers. I would support to have
additional mutex before mux as that will make less chance that someone
forgets to lock mutex before mux and proposed solution seems valid.

Regards,
Crt
