drivers/char/tty_io.c: Avoid panic when no console is configured.

2008-12-01T16:19:10+00:00

When no console is configured tty_open tries to call kref_get on a NULL
pointer, return ENODEV instead.

device create: char: convert device_create_drvdata to device_create

2008-10-16T16:24:42+00:00

Now that device_create() has been audited, rename things back to the
original call to be sane.

tty: make sure that proc_clear_tty stores the cpu flags

2008-10-15T17:19:51+00:00

proc_clear_tty() gets called with interrupts off (while holding the task list
lock) from sys_setid. This means that it needs the _irqsave version of the
locking primitives.

tty: simplify ktermios allocation

2008-10-13T16:51:44+00:00

Copy the simplification from the pty unix98 special case to the generic one.
This allows us to kill off driver->termios_locked entirely which is nice. We
have to whack bits of the cris driver as it meddles in places it shouldn't
providing its own arrays that were never used anyway.

Add an instance parameter devpts interfaces

2008-10-13T16:51:43+00:00

Pass-in 'inode' or 'tty' parameter to devpts interfaces.  With multiple
devpts instances, these parameters will be used in subsequent patches
to identify the instance of devpts mounted. The parameters also help
simplify devpts implementation.

Changelog[v3]:
	- minor changes due to merge with ttydev updates
	- rename parameters to emphasize they are ptmx or pts inodes
	- pass-in tty_struct * to devpts_pty_kill() (this will help
	  cleanup the get_node() call in a subsequent patch)

Move tty lookup/reopen to caller

2008-10-13T16:51:43+00:00

Move tty_driver_lookup_tty() and tty_reopen() from tty_init_dev()
into tty_open() (one of the two callers of tty_init_dev()).  These
calls are not really required in ptmx_open(), the other caller,
since ptmx_open() would be setting up a new tty.

Changelog[v2]:
	- remove the lookup and reopen calls from ptmx_open
	- merge with recent changes to ttydev tree

tty: extract the pty init time special cases

2008-10-13T16:51:43+00:00

The majority of the remaining init_dev code is pty special cases. We
refactor this code into the driver->install method.

tty: More driver operations

2008-10-13T16:51:42+00:00

We have the lookup operation abstracted which is nice for pty cleanup but
we really want to abstract the add/remove entries as well so that we can
pull the pty code out of the tty core and create a clear defined interface
for the tty driver table.
