This reverts commit 5f05285df691b1e82108eead7165feae238c95ef. This commit assumes that every HID descriptor for ALS sensor has presence of usage id ID HID_USAGE_SENSOR_LIGHT_COLOR_TEMPERATURE. When the above usage id is absent, driver probe fails. This breaks ALS sensor functionality on many platforms. Till we have a good solution, revert this commit.
