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

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