My concern is related that there are two different setup for the irq.
Near the client structure, the driver uses a an own platform data
structure edt_ft5x06_platform_data, where one filed is irq_pin. In whole
driver the pdata->irq_pin is used, and client->irq is used only for
requesting the irq.

But they contain the same information, as the irq number can be get easy
from irq_pin with gpio_to_irq(). Having both, it is possible to set them
to different values, and this is wrong.

Regards,
Stefano
