Hi Yasin,
Some good reviews in already for this version, so I only took a quick look
this time. It seems to be in a reasonable state now.

Hi Jonathan,
Thank you for your very patient guidance. I have updated according to
each reviewer's suggestions.
Best regards,

Add a comment explaining the data this mutex is protecting
(that may be in this structure, or for example on the device)
Done, you will see this comment in V7.

Run checkpatch.pl --strict and it will probably moan about these.
if (data->ch_data[i].sel_diff) is the same thing so just use that.
Done, and I have fixed the issues identified by the script.
