Robert Woerle cc071acaa2 Input: edt-ft5x06 - fix an i2c write for M09 support
The driver sends 3 bytes instead of 2 when accessing a register on the M09
firmware, so writing to gain seems to overflow into the offset register.

The if condition was accidentally deleted here so we return every time
instead of returning on error.

Lothar Waßmann c080846749 Input: edt-ft5x06 - adjust delays to conform datasheet
The FT5x06 datasheet specifies a minimum reset width of 5ms and a
delay between deassertion of reset and start of reporting of 300ms.
Adjust the delays to conform to the datasheet.

With the original delays I sometimes experienced communication
timeouts when initializing the controller.

Jingoo Han c838cb3d47 Input: use dev_get_platdata()
Use the wrapper function for retrieving the platform data instead
of accessing dev->platform_data directly. This is a cosmetic change
to make the code simpler and enhance the readability.
