Re: [PATCH 2/2 v3] Input: atmel_mxt_ts - Make CHG line high after the interrupts are enabled

[Iiro Valkonen <iiro.valkonen@atmel.com>]

Make the CHG line (interrupt line) go high after the interrupts have been enabled to make sure
we don't miss the falling edge.

v3: Change the locations where this is done to ensure correct operation at FW update, 
    and to get rid of some error handling
