Subject: [PATCH] blutetooth: Remove bogus inline for l2cap_chan_connect()

commit 03a001948166d966d0d580cddb8ae3a23f8b795b ("Bluetooth: invert locking
order in connect path") marked l2cap_chan_connect() inline for both the
prototype in include/net/bluetooth/l2cap.h and the implementation in
net/bluetooth/l2cap_core.c.

As the former doesn't contain an implementation, net/bluetooth/l2cap_sock.c
now fails to build, e.g. for m68k allmodconfig:

    net/bluetooth/l2cap_sock.c: In function ‘l2cap_sock_connect’:
    include/net/bluetooth/l2cap.h:838: sorry, unimplemented: inlining failed in call to ‘l2cap_chan_connect’: function body not available
    net/bluetooth/l2cap_sock.c:126: sorry, unimplemented: called from here
    make[1]: *** [net/bluetooth/l2cap_sock.o] Error 1

As l2cap_chan_connect() is not that small and also called from
net/bluetooth/l2cap_sock.c, I removed both inline keywords.

As I can't seem to find anyone else getting this, I guess it's only
triggered by some versions of gcc. Mine is

gcc version 4.1.2 20061115 (prerelease) (Ubuntu 4.1.1-21)
