This patch is a good one; however, in Greg's pile of unmerged patches is a
completely different driver for the RTL8192E. The new driver has the advantage
of being organized much more like the drivers in rtlwifi. That will make it
easier to convert to mac80211 and move to mainline.
I also have a lot of unsubmitted patches to clean up the code in the new driver.
At the moment, it is clear of 'checkpatch -f' errors, and most warnings. In
addition, many of the sparse warnings are fixed. Once Greg merges the patches
already submitted, I will send the others.
