From d7e5e76b6f4c5848ad3093493bdb226c27d8350e Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Tue, 28 Jan 2014 15:16:51 -0800 Subject: Bluetooth: Always use l2cap_chan->psm for returning PSM to user space The l2cap_chan->psm value is always set to a valid value for a connection oriented channel. The l2cap_chan->sport is used for tracking local PSM allocations but will not always have a proper value, such as with connected sockets derived from a listening socket. This patch fixes the sock_getname callback to always use chan->psm when returning address information.
