From b42fbed6b8a5942e9f76ec8c7f9c9fd798a2d3af Mon Sep 17 00:00:00 2001

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