Really?

checkpatch bleats a --strict message:

CHECK: No space is necessary after a cast
#5: FILE: t.c:5:
+
+	bar = *(int *) foo;

It's 2/1 no space v space in drivers/net and net.


$ git grep -E "\*\) " drivers/net net | wc -l
4293
$ git grep -E "\*\)[^ ;]" drivers/net net | wc -l
8261

There are many false positives in the first case,
not too many for the second.

I was a bit surprised about how many of the
first case existed.
