Should the name string be "USB-PERIPHERAL"?

> + [EXTCON_USB_HOST] = "EXTCON_USB_HOST",

Why prefix EXTCON and change hyphen to underscore?
Wasn't the original version i.e. "USB-HOST" better?

Why the change in the name strings? Who is the end user of the name string?
If the end use is just for information to a human user then the human readable
format makes more sense. i.e. "MHL" or "MICROPHONE" makes more sense than
"EXTCON_DISP_MHL" or "EXTCON_JACK_MICROPHONE"
