[dpdk-dev] [PATCH 2/2] devtools: auto detect branch to search fix patches

[Xueming Li <xuemingl@nvidia.com>]

Current fix scan scripts scanned specified range in current(HEAD)
branch. When users run it in a earlier branch, few patches were
scanned.

This patch auto etects branch to scan from range.

Fixes: 752d8e097ec1 ("scripts: show fixes with release version of bug")
