If anyone has any objections, please let me know. ------------------ From: Svyatoslav Ryhel [ Upstream commit 6bca94e64255053ab2aa56f2588fda73d399b790 ] Temperature IIO channel data is provided in milli-degrees, while POWER_SUPPLY_PROP_TEMP is expected to be in deci-degrees. Adjust the existing logic to reflect this conversion properly.
