Alexander A. Klimov ad736c1a4d hwmon: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Description
-----------
This driver implements support for Texas Instruments TMP421, TMP422,
TMP423, TMP441, and TMP442 temperature sensor chips. These chips
implement one local and up to one (TMP421, TMP441), up to two (TMP422,
TMP442) or up to three (TMP423) remote sensors. Temperature is measured
in degrees Celsius. The chips are wired over I2C/SMBus and specified
over a temperature range of -40 to +125 degrees Celsius. Resolution
for both the local and remote channels is 0.0625 degree C.
The chips support only temperature measurement. The driver exports
the temperature values via the following sysfs files:
**temp[1-4]_input**
**temp[2-4]_fault**
