This removes the private hiddev_table in the usbhid
driver and changes it to use usb_find_interface
instead.
The advantage is that we can avoid the race between
usb_register_dev and usb_open and no longer need the
big kernel lock.
This doesn't introduce race condition -- the intf pointer could be
invalidated only in hiddev_disconnect() through usb_deregister_dev(),
but that will block on minor_rwsem and not actually remove the device
until usb_open().

Dance pads don't have any axes/sticks, only buttons for directions. For
example buttons like left+right will get triggered at once, an axis
can't handle this anyway. So this patch adds a module parameter named
"sticks_to_null" for unknown devices. A known dance pad makes use of
it by changing to a new mapping-option named DANCEPAD_MAP_CONFIG. Other
tested devices may follow by adding this mapping-option too.
Some buttons of xpad-devices are addressing mouse-buttons instead of
gamepad-buttons. This gets fixed too.

UBIFS tries to alway have an LEB reserved for GC, and stores it
in c->gc_lnum. Besides, there is GC head which points to the current
GC head LEB.
In case of an unclean power cut, what may happen is that the GC head
was switched to the reserved GC LEB (c->gc_lnum), but a new reserved
GC LEB was not created yet. So, after an unclean reboot we may have
no reserved GC LEB, and we need to find a new LEB for this.
To do this, we find a dirty LEB which can fit the current GC head,
move the data, unmap this dirty LEB, and it becomes our reserved GC
LEB.
However, if we cannot find a dirty enough LEB, we return failure,
which is wrong, because we still can have free LEBs to use for
the reserved GC LEB. This patch fixes the issue.
This patch also fixes few typos in comments, which were spotted by
aspell.
Note, this patch fixes a real issue

All these files use the big kernel lock in a trivial
way to serialize their private file operations,
typically resulting from an earlier semi-automatic
pushdown from VFS.
None of these drivers appears to want to lock against
other code, and they all use the BKL as the top-level
lock in their file operations, meaning that there
is no lock-order inversion problem.
Consequently, we can remove the BKL completely,
replacing it with a per-file mutex in every case.
Using a scripted approach means we can avoid
typos.
