Submission on top of the previous patch instead of a clean v2,
subject still starting with [PATCH]{PATCH], no change log,
delta_read_word_data() and delta_read_byte_data() still as
unnecessary as before, and, worst of all, "is for the sole use
of the intended recipient(s) and may contain confidential and
privileged information" trailer.
I should not even reply to this e-mail. Please study and follow
Documentation/hwmon/submitting-patches.rst and documents referenced
therein before resubmitting.
Thanks,
Guenter
