Subject: Bluetooth: Fix lockdep warning in L2CAP
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=26954c7f26068b6ced108806fdd39aee5cd54e6f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Bluetooth: Fix lockdep warning in L2CAP

Fix a regression from the L2CAP "rewrite" patches.
Purge the tx_q already happens on l2cap_chan_del() so we don't need it at
l2cap_disconnect_req().
