No worries about the delay - we still have plenty of time till merge
window, and I am glad to hear that you are better now.

I published the branch with your reviewed-bys:

git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input.git ib/4.11-rc3-i2c-irq-resources

Note the 'ib' prefix - I am tagging immutable branches with it. I also
dropped the old branch to avoid confusion.

Thanks for heads up. I actually do not think it will be useful for me,
as I am trying to make drivers generic and do not care about platform
quirks, and instead enhance board/platform code to give sane data to the
drivers.

I replied in thread.

Thanks.
