hwmon: (max1111) Change sysfs interface to in[0-3]_input in millivolts
This patch fixed the inconsistent max1111 sysfs interface as pointed
out by Jean Delvare:
It was pointed to me that the max1111 driver doesn't implement the
standard sysfs interface for hwmon drivers (as described in
Documentation/hwmon/sysfs-interface). It exports files adc[0-3]_in,
which
aren't part of the standard interface. Presumably these should be
renamed to in[0-3]_input. Renaming them is probably not sufficient
though, as I see no scaling done in the driver. As the MAX1111 chip has
a documented full scale of 2.048V, I take it that the LSB of the ADC
has a weight of 8 mV. Exporting raw register values to user-space is
not OK.
