This patch adds support for the Nokia ca42 version 2 cable to the cypress_m8 driver. The device was tested by others with this patch and found to be compatible with the cypress_m8 driver. A special note should be taken that this cable seems to vary in the type of chipset used. This patch supports the cable with product id 0x4101.
