Subject: [PATCH 2/2] checkpatch: skip directories in file checking mode

From: Rob Herring <robh@...nel.org>

Running checkpatch.pl on a list of files using a wildcard will exit if
a directory is encountered. For example:

$ scripts/checkpatch.pl -f arch/*
diff: arch/alpha/null: No such file or directory

The correct operation is arch/Kconfig should be checked. Fix this by
skipping files which are not regular files.
