- spidev: BKL pushdown · 609f9e92
  Jonathan Corbet authored May 16, 2008

Add the BKL to spidev_open(), even though the existing locking looks
adequate.

- Add "no BKL needed" comments to several drivers · d21c95c5
  Jonathan Corbet authored May 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.

- usbcore: cdev lock_kernel() pushdown · 20613f24
  Jonathan Corbet authored May 15, 2008
```
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.

particular).
