tty: Remove tty_port::close_wait

2015-10-18T04:11:29Z

With the removal of tty_wait_until_sent_from_close(), tty drivers no longer wait during open for parallel closes to complete (instead, the tty core waits before calling the driver open() method). Thus, the close_wait waitqueue is no longer used for waiting. Remove struct tty_port::close_wait. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

tty: Remove ASYNC_CLOSING checks in open()/hangup() methods

2015-10-18T04:11:29Z

Since at least before 2.6.30, tty drivers that do not drop the tty lock while closing cannot observe ASYNC_CLOSING set while holding the tty lock; this includes the tty driver's open() and hangup() methods, since the tty core calls these methods holding the tty lock. For these drivers, waiting for ASYNC_CLOSING to clear while opening is not required, since this condition cannot occur. Similarly, even when the open() method drops and reacquires the tty lock after blocking, ASYNC_CLOSING cannot be set (again, for drivers that do not drop the tty lock while closing). Now that tty port drivers no longer drop the tty lock while closing (since 'tty: Remove tty_wait_until_sent_from_close()'), the same conditions apply: waiting for ASYNC_CLOSING to clear while opening is not required, nor is re-checking ASYNC_CLOSING after dropping and reacquiring the tty lock while blocking (eg., in *_block_til_ready()). Note: The ASYNC_CLOSING flag state is still maintained since several bitrotting drivers use it for (dubious) other purposes. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

TTY: fix misspelling of current function in string

2015-01-09T22:38:15Z

Replace a misspelled function name by %s and then __func__. This was done using Coccinelle, including the use of Levenshtein distance, as proposed by Rasmus Villemoes. Signed-off-by: Julia Lawall Signed-off-by: Greg Kroah-Hartman

tty: remove DEFINE_PCI_DEVICE_TABLE macro

2013-12-09T01:09:07Z

Don't use DEFINE_PCI_DEVICE_TABLE macro, because this macro is not preferred. Signed-off-by: Jingoo Han Signed-off-by: Greg Kroah-Hartman

TTY: rocket, fix more no-PCI warnings

2013-05-20T19:15:59Z

Commit "TTY: rocket, fix compilation warning" fixed a compilation warning, but there was still a problem with !CONFIG_PCI configs. So fix them for good by coupling the PCI functions together and moving them inside a common #ifdef. Signed-off-by: Jiri Slaby Reported-by: kbuild test robot Signed-off-by: Greg Kroah-Hartman

TTY: rocket, fix compilation warning

2013-04-15T18:00:59Z

When CONFIG_PCI is unset, we see these warnings in rocket: drivers/tty/rocket.c:3140:13: warning: 'rmSpeakerReset' defined but not used drivers/tty/rocket.c:2599:12: warning: 'sPCIInitController' defined but not used Fix those by moving the functions to one place and make them depend on CONFIG_PCI.

TTY: cleanup tty->hw_stopped uses

2013-03-18T23:24:30Z

tty->hw_stopped is set only by drivers to remember HW state. If it is never set to 1 in a particular driver, there is no need to check it in the driver at all. Remove such checks. Signed-off-by: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

TTY: add tty_port_tty_hangup helper

2013-03-18T23:24:29Z

It allows for cleaning up on a considerable amount of places. They did port_get, hangup, kref_put. Now the only thing needed is to call tty_port_tty_hangup which does exactly that. And they can also decide whether to consider CLOCAL or completely ignore that. Signed-off-by: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

tty: rocket: Explicitly list supported PCI IDs

2013-01-18T01:28:39Z

Matching PCI_ANY_ID causes conflicts with RocketPort 2 adapters, which are supported by a different driver. Signed-off-by: Kevin Cernekee Signed-off-by: Greg Kroah-Hartman

tty: add parenthesis to macro POLL_PERIOD in rocket.c
