Subject: [PATCH] checkpatch: fix camel case seeding when run with --root avoids warning about camel case of some definitions by
seeding a file that tracks all of the currently committed camel case

To build this seed file, decides between using git or the
--root parameter.

This works as long as you don't run from within
a different git tree that is not the Linux kernel.

In this case, the check for ".git" will return true, and checkpatch will
attempt to seed a camel case file using the current directory. This
works fine if --root is not provided, but can result in an incorrect
camel case seed file resulting in false positive warnings.

Fix this by checking for $root/.git instead, so that we use the --root
parameter properly when seeding the camel case list.

Additionally, when generating the list of files to be checked, prefix
the $root path so that the correct file will be found.

These changes allow to honor the --root parameter even if
being run from within another git repository.
