      wil6210: use 'uint64_t' instead of 'cycles_t' to avoid warnings · c20e7789
      Chen Gang authored
      do_div() checks the type strictly. 'cycles_t' may be 32-bit under quite
      a few architectures (parisc, arm, avr32 ...). So use 'uint64_t' instead
      of, the related warning (with allmodconfig under parisc):
