SubjectRe: [PATCH RESEND 0/3] Add quirk for reading BD_ADDR from fwnode property
From

Hi Matthias,

I am getting compiler warnings when trying to apply this set:

CC drivers/bluetooth/btqcomsmd.o
drivers/bluetooth/btqcomsmd.c: In function ‘btqcomsmd_setup’:
drivers/bluetooth/btqcomsmd.c:120:6: warning: unused variable ‘err’ [-Wunused-variable]
int err;
^~~
drivers/bluetooth/btqcomsmd.c:118:20: warning: unused variable ‘btq’ [-Wunused-variable]
struct btqcomsmd *btq = hci_get_drvdata(hdev);
^~~

Regards

Marcel
