I believe that the core already protects against a particular driver doing the registration more than once, but an analysis of the code reveals that the identical name is used for the rtlwifi drivers in the regular wireless tree, and the staging drivers r8192ee and r8821ae. The fix is to rename the algorithm used in r8192ee.
