   4 Subject: [PATCH] rtl8xxxu: Stop log spam from each successful interrupt
   5
   6 As soon as debugging is turned on, the logs are filled with messages
   7 reporting the interrupt status. As this quantity is usually zero, this
   8 output is not needed. In fact, there will be a report if the status is
   9 not zero, thus the debug line in question could probably be deleted.
  10 Rather than taking that action, I have changed it to only be printed
  11 when the newly added RTL8XXXU_DEBUG_INTERRUPT bit is set in the debug
  12 mask.
