[PATCH] iio: adc: Fix coding style violations

[Michal Simek]

From: Sai Krishna Potthuri <lakshmi.sai.krishna.potthuri at xilinx.com>

This patch fix following checkpatch warnings in xadc driver
1. Prefer 'unsigned int' to bare use of 'unsigned'.
2. else is not generally useful after a break or return.
3. function definition argument 'struct xadc *' should also
have an identifier name.
