Hi Shraddha,

Good to see someone looking at these rather neglected drivers ;)

Anyhow, in a few cases here you have converted a single bit write
within a larger field (2 or 3 bits) over to the BIT macro.
This makes the code harder to read so should not be done.

The rest of the changes are good!

Not this one.  We are writing a 1 to a 2 bit field here so BIT(5) is misleading.

Again, these are different values being written to a 3 bit field

Re: [PATCH 3/5] Staging: iio: cdc: ad7152: Fix alignment should match open parenthesis

This is always a fun one.  Making the alignment fixes promptly breaks
the 80 character guidance (which is often why the alignment is deliberately wrong)
If it can't be done without breaking that rule, I'd argue that the code is more
readable with the shortened alignment.

Always take checkpath suggestions as advice rather than a rule as
sometimes they can be less than helpful!

Applied to the togreg branch of iio.git - initially pushed out as testing
for the autobuilders to play with it.
