From 980e1a537fed7dfa53e9a4b6e586b43341f8c2d5 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Sat, 22 Jan 2011 06:10:07 +0200 Subject: Bluetooth: Add support for PIN code handling in the management interface This patch adds the necessary commands and events needed to communicate PIN code related actions between the kernel and userspace. This includes a pin_code_request event as well as pin_code_reply and pin_code_negative_reply commands. Signed-off-by: Johan Hedberg Signed-off-by: Gustavo F.
