Your patch numbering sucks.  Isolated patches should just use [PATCH], 
not [PATCH 3/3], [PATCH 4/4], etc.

Also, could you mention the name of the COMEDI driver in the patch 
title, e.g.:

[PATCH] comedi: pcmmio: Fix coding style - use BIT macro

The whitespace is a bit strange here as 'BIT(7)' no longer lines up with 
the surrounding lines.

The 'BIT(2)' also does not line up with the surrounding lines.
