This creates symlinks in /sys/class/input/ to the nested class devices
to help userspace cope with the nesting.
Unfortunatly udev still needs to be updated as it can't handle symlinks
properly here :(

The previous patch adding the ability to nest struct class_device
changed the paramaters to the call class_device_create(). This patch
fixes up all in-kernel users of the function.

I've tested it with a Logitech WingMan Rumblepad on an x86-64
machine, and on an ia32 machine to make sure I didn't break
anything.

EVIOCSKEYCODE macros to be <= KEY_MAX. Check off-by one mistakes
in keycodemax usage. There was a lot of potential for overwriting
memory. Also enlarge NR_KEYS to 256 while we're at it.

Trivial annotations in drivers/input

This patch adds sysfs support for all input devices. It also provides
the "device" and "driver" symlink for all Input devices that specify it.

Input: Introduce an optional blacklist field in input_handler structure.
When loading a new device or a new handler try to match device
against handler's black list before doing match on required
attributes.
This allows to get rid of "surprises" in connect functions, IMO
connect should only fail when it physically can not connect, not
because it decides it does not like device.

new helper - iminor(inode); defined as minor(inode->i_rdev); lots and
lots of places in drivers had been switched to it.

From: Christoph Hellwig <hch@lst.de>
Some people may already have noticed that I've been revamping the devfs API
recently. The worst offender still left is devfs_register, it's prototype
is:
devfs_handle_t devfs_register(devfs_handle_t dir,
const char *name, unsigned int flags,
unsigned int major, unsigned int minor,
umode_t mode, void *ops, void *info)
Of these:
- dir and flags are always zero
- the return value is never used
- info is only used in one driver which doesn't even need it for
operation
- umode_t always describes a character device
- name very often comes from a stack buffer we sprintf'ed into
so obviously we really want a much simpler API instead. My first draft for
this was:
int devfs_mk_cdev(dev_t dev, umode_t mode,
struct file_operations *fops, void *info,
const char *fmt, ...)
this removes the unused argumens, switches to a proper dev_t for the device
number and allows to directly use a printf-like expression as name, getting
rid of the temporary buffers.
Now Al has reappeared and put the first steps of his CIDR for charater device
on public ftp and we'll soon have a similar lookup object + fops mechanism in
generic code as we already habe for blockdevices, i.e. the devfs code to
assign fops from an entry will become superflous as generic code already does
it. That means the fops and info arguments are obsolete before they were
introduced, so I'd like to propose the following API instead:
int devfs_mk_cdev(dev_t dev, umode_t mode, const char *fmt, ...)
which is much nicer anyway. The educated reader will notice that this is
exactly the same prototype devfs_mk_bdev has so I'll probably get suggestions
to merge those two into some kind of devfs_mk_node soon. Personally I don't
like that as character and blockdevices are two really separate entinities
and I'll like to keep them as separate as possible.
Example patch that introduces the API and converts drivers/input attached.
Every driver which calls devfs_mk_cdev (about 50) needs conversion. Note
that the transition can happen in pieces - devfs_register continues to work
after this patch, it's just the plan to get rid of it in the end.

|
|
Now that devfs_handle_t is gone from all structs there is no
reason to include it in headers.
Fix the fallout by including previously implicit headers and fixing
the drivers that didn't include devfs_fs_kernel.h explicitly.
|
|
Make sure input always uses devfs_remove. While at it I've also
remove lots of code duplication - every upper input driver contained
the code surrounding devfs_unregister in two identical copies.

|
- relax requirements on devices, joydev now allows joysticks
without buttons to work with throttles and pedals, mousedev
allows a separate mouse wheel
- remove a stray semicolon in joydev

Fix cli() breakage in input (gameport) drivers.

This patch updates the input core to the current version, fixing a bunch
of bugs, adding hotplug support and a listing of available input devices
in /proc. The later is very useful for troubleshooting.
