SubjectRe: [PATCH] extcon: Introduce EXTCON_PROP_DISP_HPD property

What is meaning of HPD? So, you need to add the
description and reference for HPD in commit message.

For example,
When adding EXTCON_PROP_USB_SS property[1],
the commit message included the reference for USB SuperSpeed.

You should add the full name of 'HPD'.
