From 3af8ace653c83c663d4b97c6ea7f01463d366bf9 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Tue, 3 Dec 2013 09:51:51 +0200 Subject: [PATCH] Bluetooth: Reject LE CoC commands when the feature is not enabled Since LE CoC support needs to be enabled through a module option for now we need to reject any related signaling PDUs in addition to rejecting the creation of LE CoC sockets (which we already do).
