Ok, so you didn't even bother to write two distinct commit messages for your two patches, and my comments to the first patch apply also here. > Signed-off-by: Ian W MORRISON <ianwmorrison@xxxxxxxxx> > --- > drivers/bluetooth/Kconfig | 1 + > 1 file changed, 1 insertion(+) > > diff --git a/drivers/bluetooth/Kconfig b/drivers/bluetooth/Kconfig > index fae5a74dc737..8d432ee9f4bd 100644 > --- a/drivers/bluetooth/Kconfig > +++ b/drivers/bluetooth/Kconfig > @@ -171,6 +171,7 @@ config BT_HCIUART_BCM > depends on BT_HCIUART_SERDEV > select BT_HCIUART_H4 > select BT_BCM > + select SERIAL_DEV_CTRL_TTYPORT I think depends on (!ACPI || SERIAL_DEV_CTRL_TTYPORT) or just depends on SERIAL_DEV_CTRL_TTYPORT is what we want here, but that's still being discussed. [ In general, select should be avoided as you could end up with options enabled without their dependencies also being enabled. In this case, we're fine as BT_HCIUART_BCM as depends on SERIAL_DEV_BUS via BT_HCIUART_SERDEV, and your first patch ruled out SERIAL_DEV_BUS=y, but that's not obvious. ] > help > The Broadcom protocol support enables Bluetooth HCI over serial > port interface for Broadcom Bluetooth controllers.
