[PATCH 1/3] comedi: checkpatch error: tabs instead of spaces

From: Andreas Siegling
Date: Sun Dec 28 2014 - 13:56:54 EST

This patch fixes all occurrences of 8 whitespaces instead of a tab.
It will remove the 8 whitespaces and replace them with a tab, thereby
the checkpatch-error:
ERROR: code indent should use tabs where possible
is removed from all files in drivers/staging/comedi/
It also brings some consistency of indentation in the comments.
