Subject: [PATCH] Bluetooth: btbcm: allow btbcm_read_verbose_config to fail on
|
||
|
|
Apple
|
||
|
|
|
||
|
|
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.
