From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Date: Tue, 14 Jul 2015 16:25:30 -0400 From: Chris Mason To: Marcel Holtmann CC: Subject: [PATCH v2] Bluetooth: btbcm: allow btbcm_read_verbose_config to fail on Apple Message-ID: <20150714202530.GD27622@ret.masoncoding.com> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" List-ID: 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.
