Thanks!

I also removed the patch from 'gnu/local.mk' and made some small edits
to the commit message.

Pushed as f24aaa81de8c709adfda2e89271c562a5ca8d959

-Subject: [PATCH] HID accepts bonded device connections only.
-
-This change adds a configuration for platforms to choose a more secure
-posture for the HID profile.  While some older mice are known to not
-support pairing or encryption, some platform may choose a more secure
-posture by requiring the device to be bonded  and require the
-connection to be encrypted when bonding is required.
