From 4ae14301c3b180adaf6b72285499e7404819a023 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Sun, 20 Jan 2013 14:27:13 +0200 Subject: [PATCH] Bluetooth: Fix checking for correct mgmt_load_link_keys parameters The debug_keys parameter is only allowed to have the values 0x00 and 0x01. Any other value should result in a proper command status with MGMT_STATUS_INVALID_PARAMS.
