SubjectFwd: Request to add bluetooth module identifier to net/rfkill/rfkill-gpio.c
Hi,

I have a Cherry Trail laptop with an Atom X5-Z8300. It has a bluetooth
chip that needs the r8723bs (coexisting RTL 8723BS wifi and
bluetooth).

I am using linux-next (20150817) with the r8723bs staging driver and
the firmware and utility from https://github.com/lwfinger/rtl8723bs_bt
by Larry finger.

With linux-next the bluetooth works SOMETIMES, but on reboot, it does
not work any more (no bluetooth interfaces are detected and hciconfig
shows nothing).

I am a kernel novice, but I saw that another kernel that I had tried
had the following line added in struct acpi_device_id
rfkill_acpi_match:

{ "OBDA8723",RFKILL_TYPE_BLUETOOTH }

With the attached patch applied (one line added), my bluetooth works every time.

Does this belong in rfkill-gpio.c, or should I contact someone else?
