git bisect log info - intel_dp.c/v3.9.5-v3.10.10

1. The total commits regarding intel_dp.c between v3.9.5 and v3.10.10 are about
44 records (see git_bisect_v3.9.5_v3.10.10_intel_dp.log that I attached to this
thread)
2. Please advise if you have any suggestions to improve the trial and error
process.

git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
cd linux-stable
git bisect --start drivers/gpu/drm/i915/intel_dp.c
git bisect bad v3.10.10
git bisect good v3.9.5
git bisect view --stat > git_bisect_v3.9.5_v3.10.10_intel_dp.log
cat git_bisect_v3.10.10_intel_dp.log | grep 'Author' | wc -l
