From: Pavan Nikhilesh <pbhagavatula at marvell.com>
When longest prefix match doesnt find a suitable tree, remove the
trees of files belonging to 'drivers/common' and check if there
is any unique tree for the patchset.

v2 Chnages:
- Find tree by removing 'drivers/common' instead of count based
approach.
