Subject: Bug in checkpatch.pl

I have stumbled about a bug in checkpatch.pl while working on some
code in drivers/staging. It seems to get confused when confronted with
asterisks. For example, this snippe:

kmalloc(sizeof(struct alphatrack_ocmd) * true_size, GFP_KERNEL);

Here the asterisk is in it's binary form, obviously, and performs a
multiplication, however checkpatch reports this:

drivers/staging/frontier/alphatrack.c:772: ERROR: space prohibited
after that '*' (ctx:WxW)

So it's obviously thinking it's the unary operator, which should only
be preceded by a variable name or another unary operator such as ++.
