tty: move a number of tty drivers from drivers/char/ to drivers/tty/

2011-02-23T00:14:56+00:00

As planned by Arnd Bergmann, this moves the following drivers from
drivers/char/ to drivers/tty/ as that's where they really belong:
	amiserial
	nozomi
	synclink
	rocket
	cyclades
	moxa
	mxser
	isicom
	bfin_jtag_comm

tty: now phase out the ioctl file pointer for good

2011-02-17T19:59:56+00:00

Only oddities here are a couple of drivers that bogusly called the ldisc
helpers instead of returning -ENOIOCTLCMD. Fix the bug and the rest goes
away.

tiocmset: kill the file pointer argument

2011-02-17T19:52:43+00:00

Doing tiocmget was such fun we should do tiocmset as well for the same
reasons

tiocmget: kill off the passing of the struct file

2011-02-17T19:47:33+00:00

We don't actually need this and it causes problems for internal use of
this functionality. Currently there is a single use of the FILE * pointer.
That is the serial core which uses it to check tty_hung_up_p. However if
that is true then IO_ERROR is also already set so the check may be removed.

BKL: remove extraneous #include

2010-11-17T16:59:32+00:00

The big kernel lock has been removed from all these files at some point,
leaving only the #include.

Remove this too as a cleanup.

amiserial: Remove unused variable icount

2010-11-11T18:51:35+00:00

drivers/char/amiserial.c: In function ?rs_ioctl?:
drivers/char/amiserial.c:1302: warning: unused variable ?icount?

commit 0587102cf9f427c185bfdeb2cef41e13ee0264b1 ("tty: icount changeover for
other main devices") removed the users, but not the actual variable.

tty: icount changeover for other main devices

Again basically cut and paste

tty: release BTM while sleeping in block_til_ready

2010-08-10T20:47:44+00:00

Most tty drivers may block while opening a device.
Since this possibly depends on another thread
closing it first and both threads may need the BTM,
we need to release it here.

tty: untangle locking of wait_until_sent

2010-08-10T20:47:43+00:00

Some wait_until_sent versions require the big
tty mutex, others don't and some callers of
wait_until_sent already hold it while other don't.
That leads to recursive use of the BTM in these
functions, which we're trying to get rid of.

This turns all cleans up the locking there so
that the driver's wait_until_sent function
never takes the BTM itself if it is already
called with that lock held.

tty: replace BKL with a new tty_lock

2010-08-10T20:47:43+00:00

As a preparation for replacing the big kernel lock
in the TTY layer, wrap all the callers in new
macros tty_lock, tty_lock_nested and tty_unlock.
