  Add "no BKL needed" comments to several drivers · d21c95c5
  由 Jonathan Corbet 提交于 5月 16, 2008
```
This documents the fact that somebody looked at the relevant open()
functions and concluded that, due to their trivial nature, no locking was
needed.

usb_open() is protected by a down_read(&minor_rwsem), but I'm not sure I
trust it to protect everything including subsidiary open() functions.
