I think this change is OK.  However you'll notice that checkpatch.pl
has three categories of issues that get reported:  errors, warnings,
and checks.  These are in decreasing order of severity.

Alignment issues like this are just "checks", which means they are
minor nits that are often not considered a "real" problem.  In many
cases, white space variances like this are done intentionally, to
make the code more readable, or sometimes simply because the code
that surrounds it used a different convention for alignment (some
people simply align to an even number of tabs, for example).

In this case, the change doesn't make the "look" of the code any
worse, and doesn't reduce readability.  It furthermore gets rid
of spaces after a tab that do *not* lead to the suggested alignment.
It probably isn't a necessary change, but I think it's reasonable.

I write all this to explain that these sorts of changes are in many
cases rejected.

I'll leave it to Greg to accept this, or offer a second opinion.
