This patch replaces bit shifting on 1 with the BIT(x) macro.

This was done with coccinelle:

@@ int g; @@

-(1 << g)
+BIT(g)

Good straight forward cases.  Applied to the togreg branch of iio.git.
Will be initially pushed out as testing for the autobuilders to play with
it.

Thanks,

Jonathan

A small process related point.  These are reworked versions of your
earlier series.  Please make that obvious with a V2 in the patch name.
A cover letter explaining what the changes were is also a useful addition.

I suspect a lot of reviewers do what I do and work backwards through their
email and hence need the indication that there is an earlier thread they
should be cross referring to.

Thanks,
Jonathan
