Bug ID: 197121
Summary: Bluetooth regression "no bluetooth adapters found"
Baytrail T100CHI (SDIO) BCM4324B3
Product: Drivers
Version: 2.5
Kernel Version: 4.14-{rc1,rc2,rc3}
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: blocking
Priority: P1
Component: Bluetooth
Assignee: linux-bluetooth@vger.kernel.org
Reporter: jbmacbrodie@yahoo.com
Regression: No
Bluetooth no longer works in 4.14. Starting Blueman device manager with kernel
4.14-rc1 produces the error "No bluetooth adapters found". Bluetooth has been
working on the T100CHI since 4.3.5 [patched with bt deviceID until 4.7]. The
CHI uses bluetooth to connect to its keyboard/touchpad.
Reverting first bad commit 33cd149e767be9afbab9fcd3d5165a2de62313c8 does not
fix bluetooth. (See report below)
Excerpt from dmesg 4.13 vs. 4.14 shows that the bluetooth binary blob is not
being loaded in 4.14. The Asus T100CHI uses the brcmfmac43241b4-sdio chip.

Bluetooth: hci_bcm: Add serdev support
Add basic support for Broadcom serial slave devices.
Probe the serial device, retrieve its maximum speed and
register a new hci uart device.
Tested/compatible with bcm43438 (RPi3).

Seems that you did not included BCM HCI UART protocol:
CONFIG_BT_HCIUART_BCM
This now depends on CONFIG_BT_HCIUART_SERDEV which depends on
CONFIG_SERIAL_DEV_BUS.

Thank you. The new dependencies had turned off CONFIG_BT_HCIUART_BCM.
