tty: Make tiocgicount a handler

2011-11-26T17:10:38Z

commit d281da7ff6f70efca0553c288bb883e8605b3862 upstream Dan Rosenberg noted that various drivers return the struct with uncleared fields. Instead of spending forever trying to stomp all the drivers that get it wrong (and every new driver) do the job in one place. This first patch adds the needed operations and hooks them up, including the needed USB midlayer and serial core plumbing.

tty, serial: Fix race and NULL check in uart_close()

2009-10-12T17:21:33Z

Commit 46d57a449aa1 ("serial: use tty_port pointers in the core code") contained two bugs that causes (rare) crashes: - the rename typoed one site - a NULL check was missed Reported-and-tested-by: Ingo Molnar Cc: Greg KH Cc: Alan Cox Signed-off-by: Ingo Molnar Signed-off-by: Linus Torvalds

Set proper console speed on resume if console suspend is disabled

2009-09-19T20:13:33Z

Commit b5b82df6, from May 2007, breaks no_console_suspend on the OLPC XO laptop. Basically what happens is that upon returning from resume, serial8250_resume_port() will reconfigure the port for high speed mode and all console output will be garbled, making debug of the resume path painful. This patch modifies uart_resume_port() to reset the port to the state it was in before we suspended. Original patch by Marcelo Tosatti Second patch by Deepak then reworked by Alan to fit with the tty changes before it got submitted. Also fixed the console path to set c_i/ospeed as some drivers require the termios fields are valid Signed-off-by: Deepak Saxena Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

serial: introduce tty krefs

2009-09-19T20:13:33Z

Initially just use the helper and thus krefs when we set and clear the port values. Signed-off-by: Alan Cox

serial: kill USF_CLOSING_* definitions

2009-09-19T20:13:32Z

The serial layer for some reason uses different defines for the special case close delays and then conditionally switches to/from the normal ones in the ioctls. Remove this rather pointless abstraction Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

serial: move port users helper

2009-09-19T20:13:32Z

This little helper is now tty_port specific and useful generally so move it Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

serial: move delta_msr_wait into the tty_port

2009-09-19T20:13:31Z

This is used by various drivers not just serial and can be extracted as commonality Signed-off-by: Alan Cox

serial: replace the state mutex with the tty port mutex

2009-09-19T20:13:31Z

They cover essentially the same stuff and we can therefore fold it into the tty_port one. Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman

serial: move the flags into the tty_port field

2009-09-19T20:13:30Z

Fortunately the serial layer was designed to use the same flag values but with different names. It has its own SUSPENDED flag which is a free slot in the ASYNC flags so we allocate it in the ASYNC flags instead. Signed-off-by: Alan Cox Signed-off-by: Greg Kroah-Hartman
