tty: Remove dead code

2013-07-26T23:19:48Z

-> The ledptrs[] array is never initialized. -> There is no place where kbd->ledmode is set to LED_SHOW_MEM therefore the if statement does not make much sense. -> Since LED_SHOW_MEM is not used, it can be removed from the header file as well.

TTY: switch tty_schedule_flip

2013-01-16T06:43:15Z

Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. This is the last one: tty_schedule_flip Signed-off-by: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

TTY: switch tty_insert_flip_char

2013-01-16T06:21:36Z

Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. tty_insert_flip_char is the next one to proceed. This one is used all over the code, so the patch is huge.

vt: fix the keyboard/led locking

2012-07-17T16:13:37Z

We touch the LED from both keyboard callback and direct paths. In one case we've got the lock held way up the call chain and in the other we haven't. This leads to complete insanity so fix it by giving the LED bits their own lock. Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

tty: keyboard.c: Remove locking from vt_get_leds.

2012-07-06T21:28:17Z

There are three call sites for this function, and all three are called within a keyboard handler. kbd_event_lock is already held within keyboard handlers, so attempting to lock it in vt_get_leds causes deadlock.

TTY: vt, remove con_schedule_flip

2012-06-14T00:30:53Z

This is identical to tty_schedule_flip. So let us use that instead. Signed-off-by: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

tty: Fix LED error return

2012-05-14T17:43:24Z

3.4-rc introduced a regression when setting the LEDS. We do the right thing but then return an error code. Resolves-bug: https://bugzilla.kernel.org/show_bug.cgi?id=43144 Reported-by: Christian Casteyde Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds

keyboard: Use BIOS Keyboard variable to set Numlock

2012-05-08T21:19:41Z

The PC BIOS does provide a NUMLOCK flag containing the desired state of this LED. This patch sets the current state according to the data in the bios.

vt: Fix deadlock on scroll-lock

2012-05-01T18:01:28Z

Fixing the locking accidentally replaced a race in the scroll lock handling with a deadlock. Turn it back into a race for now. The basic problem is that there are two paths into the tty stop/start helpers. One via the tty layer ^S/^Q handling where we need to take the kbd_event_lock and one via the special keyboard handler for fn_hold where we already hold it. Probably we need to split out into a separate LED lock but for now just go back to the race as it's a bit close to release.
