possible new false positive in checkpatch

Since my last pull from upstream (today) , I started seeing some
checkpatch warnings regarding suspect code indent I believe are false
positive. Take this code for example:

static int foo(void)
{
while (bar())
/* do nothing */;
}

When running checkpath on it, the following warning is emitted:

tal@tal:~/Dev/lfs/linux|0 $ scripts/checkpatch.pl -f ~/tmp/foo.c
WARNING: suspect code indent for conditional statements (8, 32)
#3: FILE: /home/tal/tmp/foo.c:3:
+ while (bar())
+ /* do nothing */;

total: 0 errors, 1 warnings, 5 lines checked

/home/tal/tmp/foo.c has style problems, please review.

NOTE: If any of the errors are false positives, please report
them to the maintainer, see CHECKPATCH in MAINTAINERS.
tal@tal:~/Dev/lfs/linux|1 $

Using my limited perl knowledge, I believe the lines causing this are
3111-3133:
# remove inline comments
$s =~ s/$;/ /g;
$c =~ s/$;/ /g;
Introduced in commit 9f5af480f4554aac12e002b6f5c2b04895857700:
checkpatch: improve SUSPECT_CODE_INDENT test
Commenting out these lines removes the warning.

This pattern exists in many places around the kernel source.
Is this the intended behavior?
