2010-08-02	V4L/DVB: IR/lirc: make lirc userspace and staging modules buildable	Jarod Wilson
	The lirc userspace needs all the current ioctls defined, and we need to put the header files in places out-of-tree and/or staging lirc drivers (which I plan to prep soon) can easily build with. I've actually tested this in a tree w/all the lirc drivers queued up to be submitted for staging. I'm also reasonably sure that Andy Walls is going to need most of the ioctls anyway for his cx23888 IR driver work.

2010-08-02	V4L/DVB: lirc: use unlocked_ioctl	Arnd Bergmann
	New code should not rely on the big kernel lock, so use the unlocked_ioctl file operation in lirc. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Tested-by: Jarod Wilson <jarod@redhat.com> Acked-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

This should do the trick. Completely untested beyond compiling, but its not exactly a complicated fix, and in practice, I'm not aware of anyone ever actually tripping that locking bug, so there's zero functional change in typical use here.
