If THIS_MODULE is not set, the module would be removed while debugfs is
being used.
It eventually makes kernel panic.

Wow, 117 practically identical patches? No thanks ...

Can you merge the ones that belong to a single driver?

net/mac80211/ -> mac80211
net/wireless/ -> cfg80211

etc.

I don't think we need more than one patch for each driver/subsystem.
