Applied, though renamed to mention the fact it is in the tsl2583 driver rather than
generally across the subsystem.  Will be in the togreg branch, but I initially
push that out as testing to allow the various autobuilders to play.

Thanks,

Jonathan

Hmm. I wonder if this is a little too tight on the range, but
given it is in a function that is likely to be called infrequently
it doesn't really matter.  Note this is where we find out whether
the datasheet is actually accurate is saying 3 msecs is long enough
by whether anyone screams :)

Also cc'd Jon as if anyone screams about this they are likely to do it
at him.  As a general rule, do cc the original author unless you know
there email bounces (and if so mention it in the cover letter as someone
might know where to get hold of them).

Applied to the togreg branch of iio.git - initially pushed out as testing.

Thanks,

Jonathan
