f2b9857eee Add a bunch of cycle_kernel_lock() calls 
All of the open() functions which don't need the BKL on their face may
still depend on its acquisition to serialize opens against driver
initialization.  So make those functions acquire then release the BKL to be
on the safe side.

itself seems OK, but one never knows about all the open() functions

d21c95c569 Add "no BKL needed" comments to several drivers 
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.
