Broadcom bluetooth driver bcm_dhd 1363 error in imx8 kernel 4.9.51

nsyed — Tue, 10 Jul 2018 08:05:14 GMT

, I am using imx8 based board from compulab

CL-SOM-iMX8 | NXP i.MX 8 | System-on-Module | Computer-on-Module | CompuLab

Its using 4.9.51 kernel which i got from source.codeaurora.org/external/imx/linux-imx -b imx_4.9.51_imx8mq

Then I applied real time path from preempt_RT website which was patch-4.9.47-rt37.patch and thats the closest one i found with 4.9.51 kernel.

The patch is applied Ok but after that when I do make it complains about broadcom driver (Wifi + Bluetooth) .

here is the error message
