Any comments would be appreciated.

Description: Use msleep_interruptible() instead of gt96100_delay() so
that the task delays as expected. Remove the prototype and definition of
gt96100_delay(). As I currently understand it, the check for interrupt
context is not necessary in gt96100_delay(), as such a sleep will be
caught within the scheduler.
