V4L/DVB: IR: add lirc device interface v2: currently unused ioctls are included, but #if 0'd out Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

[media] lirc_dev: store cdev in irctl, up maxdevs Store the cdev pointer in struct irctl, allocated dynamically as needed, rather than having a static array. At the same time, recycle some of the saved memory to nudge the maximum number of lirc devices supported up a ways -- its not that uncommon these days, now that we have the rc-core lirc bridge driver, to see a system with at least 4 raw IR receivers. (consider a mythtv backend with several video capture devices and the possible need for IR transmit hardware).

[media] IR/lirc: further ioctl portability fixups >From Joris van Rantwijk <jorispubl@xs4all.nl>: I tested lirc_serial and found that it works fine. Except the LIRC ioctls do not work in my 64-bit-kernel/32-bit-user setup. I added compat_ioctl entries in the drivers to fix this. While doing so, I noticed inconsistencies in the argument type of the LIRC ioctls. All ioctls are declared in lirc.h as having argument type __u32, however there are a few places where the driver calls get_user/put_user with an unsigned long argument. The patch below changes lirc_dev and lirc_serial to use __u32 for all ioctl arguments, and adds compat_ioctl entries. It should probably also be done in the other low-level drivers, but I don't have hardware to test those. I've dropped the .compat_ioctl addition from Joris' original patch, as I swear the non-compat definition should now work for both 32-bit and 64-bit userspace. Technically, I think we still need/want a in getting a reply to you).
