Has this been applied  ?

v3.3 version of checkpatch.pl works for me, but v3.4, v3.5 & v3.6rc2 say:
Nested quantifiers in regex; marked by <-- HERE in m/(\((?:[^\(\)]++
<-- HERE |(?-1))*\))/ at scripts/checkpatch.pl line 340.

and my perl is :

        perl --version

        This is perl, v5.8.8 built for i586-linux-thread-multi
