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 Cc: Arnd Bergmann Cc: Alan Cox Cc: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

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. Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

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 Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

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.

tty: icount changeover for other main devices

2010-10-22T17:20:05+00:00

Again basically cut and paste Convert the main driver set to use the hooks for GICOUNT Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

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. Signed-off-by: Arnd Bergmann Cc: Alan Cox Signed-off-by: Greg Kroah-Hartman

synclink: reworking locking a bit

2010-08-10T20:47:41+00:00

Use the port mutex and port lock to fix the various races. The locking still isn't totally consistent but its better than before. Wants switching to the port helpers. Signed-off-by: Alan Cox Cc: Arnd Bergmann Signed-off-by: Greg Kroah-Hartman

synclink: kill the big kernel lock

2010-08-10T20:47:40+00:00

We don't need it while waiting and we can lock the ioctls using the port mutex. While at it eliminate use of the hangup mutex and switch to the port mutex. Signed-off-by: Alan Cox Cc: Arnd Bergmann Signed-off-by: Greg Kroah-Hartman

hdlc: convert to netdev_tx_t

headers: smp_lock.h redux

2009-07-12T19:22:34+00:00

* Remove smp_lock.h from files which don't need it (including some headers!) * Add smp_lock.h to files which do need it * Make smp_lock.h include conditional in hardirq.h It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT This will make hardirq.h inclusion cheaper for every PREEMPT=n config (which includes allmodconfig/allyesconfig, BTW) Signed-off-by: Alexey Dobriyan Signed-off-by: Linus Torvalds
