This reverts commit 393935baa45e5ccb9603cf7f9f020ed1bc0915f7. As reported by Ian Nartowicz, this and the next patch result in a failure to load the driver on Celsius W280. While the alternative would be to add the board to the DMI override table, it is quite likely that other systems are also affected. Revert the offending patches to avoid future problems.
