Hi Aurabindo,

No, I do not have this commit in my tree. I am currently testing on
the mainline Linux repository (Torvalds' tree), and it seems this fix
hasn't landed there yet.

I just updated to the latest master (commit c2f2b01b74be) and searched
for it, but found nothing:
mikhail@primary-ws ~/p/g/linux (master)> git remote -v
origin git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git (fetch)
origin git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git (push)

mikhail@primary-ws ~/p/g/linux (master)> git log --all --grep="Improve
HDMI info retrieval" -i --oneline
mikhail@primary-ws ~/p/g/linux (master)>

Could you please point me to the tree/branch where this fix is
located, or send it as a patch? I would be happy to apply it and test
if it resolves the regression.
