According to the tests in do_initcalls(), the proper error code in case no
device is found is -ENODEV, not -ENXIO or -EIO.

Move the line disciplines towards a conventional ->ops arrangement.  For
the moment the actual 'tty_ldisc' struct in the tty is kept as part of
the tty struct but this can then be changed if it turns out that when it
all settles down we want to refcount ldiscs separately to the tty.

Pull the ldisc code out of /proc and put it with our ldisc code.

Add "no_hpsdc" kernel module option to the hp_sdc driver, so that
the driver can be instructed to not enable the HP SDC port.

This is useful on some older HPPA boxes with HIL keyboard
and HIL mouse where the new HP SDC HIL drivers don't work
yet. By disabling the new hp_sdc driver users are able to use
the older hilkbd driver instead.

to introduce a flag.

Commit 656acd2b ("Input: fix locking in

| linux/drivers/input/ff-core.c: In function 'input_ff_upload':
| linux/drivers/input/ff-core.c:172: error: dereferencing pointer to incomplete type
| linux/drivers/input/ff-core.c: In function 'erase_effect':

| linux/drivers/input/ff-core.c:204: error: dereferencing pointer to incomplete type

As the incomplete type is `struct task_struct', including <linux/sched.h> fixes
it.

Force feedback upload of effects through the event device (ioctl
EVIOCSFF) is not working in 32 bit applications running on 64-bit
kernel due to the fact that struct ff_effect contains a pointer,
resulting in the structure having different sizes in 64 and 32 bit
programs and causing difference in ioctl numbers.

The newly added event_lock spinlock in the input core disallows sleeping
and therefore using mutexes in event handlers. Convert force-feedback
core to rely on event_lock instead of mutex to protect slots allocated
for fore-feedback effects. The original mutex is still used to serialize
uploading and erasing of effects.
