From 075e1f5e6c201111e32da99919eb052edc6d1c82 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Wed, 7 Oct 2015 20:08:26 +0200 Subject: [PATCH] Bluetooth: hci_bcm: Enable support for set_diag driver callback The set_diag driver callback allows enabling and disabling the vendor specific diagnostic information. Since Broadcom chips have support for a dedicated LM_DIAG channel, hook it up accordingly.
