2009-09-19cyclades: use dtr_rts helpersJiri Slaby
For Z cards, use tty helpers for dtr_rts. If we did the same for Y cards, it will cause a deadlock, because cyy_dtr_rts takes a lock which we already hold. Instead, we introduce a Y helper expecting card lock to be held. It may then be called with set/clear masks from other places.

2009-09-19cyclades: close cleanupJiri Slaby
Use new tty helpers for close, which allows much code removal. The only real change is locking. card_lock for protecting was used inappropriately (just to have a critical section, no matter which lock is used), so the change to port->lock is fine. Remove also useless debug printks while being there. Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-09-19cyclades: switch to tty_port_hangupJiri Slaby
Do not duplicate common tty_port_hangup code. Use it instead. Also do not unset ASYNC_NORMAL_ACTIVE and wake up from the tty_hangup() caller. It makes no sense since we don't check that flag in sleepers. tty_port_hangup() performed later will do the right job.

2009-09-19cyclades: avoid addresses recomputationJiri Slaby
Don't fetch firmware address and recompute channel control on each port access. Precompute the values on init and use them later all the time. The same for board control.

2009-09-19cyclades: remove block_til_readyJiri Slaby
Use a tty_port common instead. This saves lots of .text and makes the code a lot more readable. This involves separation of a dtr_rts handling, next patches will use that to not duplicate the code all over the place.

2009-09-19cyclades: add tty refcountingJiri Slaby
While this is not problem for Y card handlers (they are protected by card_lock), Z handlers and other functions may dereference NULL at any point after hangup/close. Even if (tty == NULL) was already performed in the handler. Note that it's not an issue for Y cards just for now. After switching to tty_port_close_* et al. this will be a problem. So add refcounting to them all. Also proc .show doesn't take a tty reference and it should (along with a ldisc one). While at it and changing prototypes (adding tty param), prepend cy_ to functions which don't have it yet.

2009-09-19tty-ldisc: get rid of tty_ldisc_try_get() helper functionLinus Torvalds
Now that the /proc/tty/ldiscs handling doesn't play games with 'struct ldisc' any more, the only remaining user of 'tty_ldisc_try_get()' is 'tty_ldisc_get()' (note the lack of 'try'). And we're actually much better off folding the logic directly into that file, since the 'try' part was always about trying to get the ldisc operations, not the ldisc itself: and making that explicit inside of 'tty_ldisc_get()' clarifies the whole semantics.

2009-09-19tty-ldisc: make /proc/tty/ldiscs use ldisc_ops instead of ldiscsLinus Torvalds
The /proc/tty/ldiscs file is totally and utterly un-interested in the "struct tty_ldisc" structures, and only cares about the underlying ldisc operations. So don't make it create a dummy 'struct ldisc' only to get a pointer to the operations, and then destroy it. Instead, we split up the function 'tty_ldisc_try_get()', and create a 'get_ldops()' helper that just looks up the ldisc operations based on the ldisc number. That makes the code simpler to read (smaller and more well-defined helper functions), and allows the /proc functions to avoid creating that useless dummy only to immediately free it again.

2009-09-19phram: cleanup error handling and associated messagesMike Frysinger
The error handling in the phram driver is pretty bad -- in many places, errors are silently ignored or logged, but then still ignored in the return value. So convert all of the code to pass back the correct return value and log error messages properly (and using the new pr_fmt() helper). If everything does go smoothly, rather than exit silently, dump a helpful info message like pretty much every other MTD driver does.

Remove the ARM dependency from the generic "onenand" platform device driver. This change makes the driver useful for other architectures as well. Needed for the SuperH kfr2r09 board. Apart from the obvious Kconfig bits, the most important change is the move away from ARM specific includes and platform data. Together with this change the only in-tree board code gets an update, and the driver name is also changed gracefully break potential out of tree drivers. The driver is also updated to allow NULL as platform data together with a few changes to make use of resource_size() and dev_name().

2009-09-19mtd: nand: register orion_nand using platform_driver_probe()Uwe Kleine-König
orion_nand_probe lives in .init.text, so using platform_driver_register to register it is wrong because binding a device after the init memory is discarded (e.g. via sysfs) results in an oops. As requested by Nicolas Pitre platform_driver_probe is used instead of moving the probe function to .devinit.text as proposed initially. This saves some memory, but devices registered after the driver is probed are not bound (probably there are none) and binding via sysfs isn't possible.
