Subject: [PATCH 4.19 38/70] platform/x86: GPD pocket fan: Allow somewhat lower/higher temperature limits

From: Hans de Goede <hdegoede@...hat.com>

[ Upstream commit 1f27dbd8265dbb379926c8f6a4453fe7fe26d7a3 ]

Allow the user to configure the fan to turn on / speed-up at lower
thresholds then before (20 degrees Celcius as minimum instead of 40) and
likewise also allow the user to delay the fan speeding-up till the
temperature hits 90 degrees Celcius (was 70).
