Ah.
What a mess.
I would recommend starting to unwind the "debugging" macro mess here,
all that a driver should be using is the netdev_dbg() and friends
functions, not this mess of "printk or no printk" that it currently is.
If you replace _dbgdump with what it is defined with, then go from there
and replace the DBG_8192C and friends with what they should be, and so
on. That's a much better overall solution than to just paper over this
with a checkpatch cleanup.
