Please, don't...
I thought we've finished discussing the regulator issue...

Instead of patching the driver and the platform data and the board file,
you should do _either_ of the following:
1) add regulator definition for ads7846 into the board file
2) enable the CONFIG_REGULATOR_DUMMY in your kernel configuration
3) use regulator_use_dummy_regulator() call in the board file.

Using either of the above, you will not need the patch for ads7846, only for the board file.
