Subject: [PATCH 0/2] w1: DS2408 fixes
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Hi,
I prepared a two fixes related with 1wire and DS2408.

In short the problem was that a single DS2408 slave was properly setting
the output value to a channel access write but the command was returning
error.
Moreover when there was a write of a 0xff value (all inputs off, there was 
also no problem - it's now also understandable for me after looking
at the transmission log) ;)
This problem doesn't occur on a multidrop bus.

Finally I was able to catch the problems recently after analyzing the
oscilloscope waveforms in PulseView.
After those fixes all is now working perfectly fine - no matter if it
is multidrop or single slave bus :)

ps. if you are merging this please also take into account a patch which
I've sent recently but it is still not merged:
