If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 7bee8b08c428b63aa4a3765bb907602e36355378 Mon Sep 17 00:00:00 2001 From: Chris Mason <clm@xxxxxx> Date: Tue, 14 Jul 2015 16:25:30 -0400 Subject: Bluetooth: btbcm: allow btbcm_read_verbose_config to fail on Apple From: Chris Mason <clm@xxxxxx> commit 7bee8b08c428b63aa4a3765bb907602e36355378 upstream. Commit 1c8ba6d013 moved around the setup code for broadcomm chips, and also added btbcm_read_verbose_config() to read extra information about the hardware. It's returning errors on some macbooks: Bluetooth: hci0: BCM: Read verbose config info failed (-16) Which makes us error out of the setup function. Since this probe isn't critical to operate the chip, this patch just changes things to carry on when it fails.
