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
