Subject: [PATCH 08/10] staging: r8188eu: remove all remaining aliased DBG_88E calls
Remove all remaining calls to preprocessor aliases of DBG_88E, as well
as these definitions themselves, so that we can finally remove DBG_88E.
This patch triggers several style related checkpatch warnings due to
line lengths, placement of constants and '+' operators being too
squished together. As these are pre-existing issues, they are better
solved with a separate patch series that is more in scope.
