[ Upstream commit d776f016d24816f15033169dcd081f077b6c10f4 ]
Temperatures are reported in units of Celsius however hwmon expects values to be in millidegree of Celsius. Userspace tools observe values close to zero and report it as "Not available" or incorrect values like 0C or 1C. Add a simple conversion to fix that.
Before the change:
wsa884x-virtual-0 Adapter: Virtual device temp1: +0.0°C -- wsa884x-virtual-0 Adapter: Virtual device temp1: +0.0°C
Also reported as N/A before first amplifier power on.
After this change and initial wsa884x power on:
wsa884x-virtual-0 Adapter: Virtual device temp1: +39.0°C -- wsa884x-virtual-0 Adapter: Virtual device temp1: +37.0°C
Tested on sm8550 only.
