Lars-Peter Clausen 93e33d7030 staging:iio:ad7476: Avoid alloc/free for each sample in buffered mode 
The ad7476 driver has only support for 1 channel ADCs. So the upper limit for
the buffer size is the size of one sample plus the size of the timestamp.
Preallocate a buffer large enough to hold this to avoid having to allocate and
free a new buffer for each sample being captured.
