Subject: [PATCH] Bluetooth: Fix not checking for valid hdev on bt_dev_{info,warn,err,dbg}
Date: Wed, 2 Mar 2022 15:08:58 -0800 [thread overview]
Message-ID: <20220302230858.444141-1-luiz.dentz@gmail.com> (raw)
From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
This fixes attemting to print hdev->name directly which causes them to
print an error:
