From e6e981c74234a6f4e1414ba11ca9746850f261a9 Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Fri, 27 Nov 2015 16:39:00 -0500 Subject: [PATCH] Bluetooth: hci_ldisc: Remove dead code The N_HCI ldisc does not define a flush_buffer() ldisc method, so the check when opening the ldisc is always false.
