Subject: hwmon: (w83627ehf) Skip reading unused voltage registers
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=389ef65d2eae579b23af719f5ef18d625f41fada;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

hwmon: (w83627ehf) Skip reading unused voltage registers

When in6 is missing, don't read the corresponding registers, it's a
waste of time. The logic is similar to what we do for fans and
temperatures.
