Merge branch 'w83977af_ir-neatening'

Joe Perches says:

====================
irda: w83977af_ir: Neatening

Originally on top of Arnd's overly long udelay patches because I
noticed a misindented block.  That's now already fixed along with some
other whitespace problems.  These patches are the remainder style
issues from my original series.

Even though I haven't turned on the netwinder in a box in the
garage in who knows how long, if this device is still used somewhere,
might as well neaten the code too.
