Hi, Please use get_maintainer.pl script when you send the patches. I didn't receive the patches. I'll review.

Sorry, I missed out on using the get_maintainer.pl script - instead, I sent it to those listed under "ARM/QUALCOMM SUPPORT" in the MAINTAINERS file as drivers/extcon/extcon-qcom* is listed in that section. Thank you. Guru Das.
