Input: wacom - prepare for syncing with input-mt changes
Henrik added new MT routines in release 3.7. This patch is to prepare for the use of new MT routines. In the newly added wacom_abs_set_axis() function, the first if-statement assigns ABS_X/Y for number of contacts less or equal to 2. So, it is single and 2 finger touch devices. Two finger touch devices are processed here since they will not use the updated input_mt_init_slots(), which does not offer benefit to those devices. input_mt_init_slots() will take care of ABS_X/Y assignment when flags are not zero. All touch devices with more than two contacts will use input_mt_init_slots() with non-zero flags. The second if-statement is for all MT devices, which include two finger touch devices.
