* [media] lirc_dev: store cdev in irctl, up maxdevsJarod Wilson2011-06-111-1/+1
| | | | | | | | | | | | | 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 fixupsJarod Wilson2010-10-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | >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).

* V4L/DVB: IR/lirc: make lirc userspace and staging modules buildableJarod Wilson2010-08-021-0/+225
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.
