Subject: Bluetooth: Reject LE CoC commands when the feature is not enabled
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3af8ace653c83c663d4b97c6ea7f01463d366bf9;p=linux-beck.git

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).
