-This driver implements support for the Winbond W83781D, W83782D, W83783S,
-W83627HF chips, and the Asus AS99127F chips. We will refer to them
-collectively as W8378* chips.

+chips, and the Asus AS99127F chips. We will refer to them collectively as
+W8378* chips.
 
 There is quite some difference between these chips, but they are similar
 enough that it was sensible to put them together in one driver.
-The W83627HF chip is assumed to be identical to the ISA W83782D.
 The Asus chips are similar to an I2C-only W83782D.

 If an alarm triggers, it will remain triggered until the hardware register
 is read at least once. This means that the cause for the alarm may
 already have disappeared! Note that in the current implementation, all
