The rtwdev->rf_lock spinlock protects the rf register accesses in rtw_read_rf() and rtw_write_rf(). Most callers of these functions hold rtwdev->mutex already with the exception of the callsites in the debugfs code. The debugfs code doesn't justify an extra lock, so acquire the mutex there as well before calling rf register accessors and drop the now unnecessary spinlock.
