| |
In case emulated temperature is in use, using the trend provided by driver layer can lead to bogus situation. In this case, debugger user would set a temperature value, but the trend would be from driver computation.
To avoid this situation, this patch changes the get_tz_trend() to consider the emulated temperature whenever that is in use.
