Subject: [PATCH] Bluetooth: trivial: tidy up printk message output from btrtl.
Date:   Mon,  9 Sep 2019 16:03:29 +0100
Message-Id: <20190909150329.1779-1-rsalvaterra@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-bluetooth-owner@vger.kernel.org
Precedence: bulk

The rtl_dev_* calls in the Realtek USB Bluetooth driver add unnecessary
device prefixes and new lines at the end of most messages, which make the
dmesg output look like this:

[    5.667121] sd 0:0:0:0: [sda] Attached SCSI disk
[    5.736869] Bluetooth: hci0: RTL: rtl: examining hci_ver=06 hci_rev=000a lmp_ver=06 lmp_subver=8821

[    5.737853] Bluetooth: hci0: RTL: rom_version status=0 version=1

[    5.737857] Bluetooth: hci0: RTL: rtl: loading rtl_bt/rtl8821a_fw.bin

[    5.737946] Bluetooth: hci0: RTL: rtl: loading rtl_bt/rtl8821a_config.bin

[    5.737965] bluetooth hci0: Direct firmware load for rtl_bt/rtl8821a_config.bin failed with error -2
[    5.737972] Bluetooth: hci0: RTL: cfg_sz -2, total sz 17428

[    5.997375] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300)

Clean this up by removing extraneous new lines and redundant device prefixes,
with the following result:

[    5.667008] sd 0:0:0:0: [sda] Attached SCSI disk
[    5.716945] Bluetooth: hci0: rtl: examining hci_ver=06 hci_rev=000a lmp_ver=06 lmp_subver=8821

[    5.718849] bluetooth hci0: Direct firmware load for rtl_bt/rtl8821a_config.bin failed with error -2
[    5.718858] Bluetooth: hci0: rtl: cfg_sz -2, total sz 17428
