[PATCH 2/3] iio: stmpe-adc: Make wait_completion non interruptible

[Philippe Schenker]

From: Philippe Schenker <philippe.schenker@xxxxxxxxxxx>

In some cases, the wait_completion got interrupted. This caused the
error-handling to mutex_unlock the function. The before turned on
interrupt then got called anyway. In the ISR then completion()
was called causing problems.

Making this wait_completion non interruptible solves the problem.
