ADC Driver.

Hello,
I have use 24Bit LTC 2448 adc chip If i implement ssleep(4) inside the
driver at the time of read/write work my touch screen is not properly work.
Its sleep 4 sec.

Wow, 24bit ... sounds serious.

Had to read a bit about ssleep()

As ssleep() is uninterruptible doesn't that mean noting else will happen
until the 4 seconds have passed.
