2013-01-15TTY: move low_latency to tty_portJiri Slaby1-1/+1
One point is to have less places where we actually need tty pointer. The other is that low_latency is bound to buffer processing and buffers are now in tty_port. So it makes sense to move low_latency to tty_port too. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-15TTY: switch tty_insert_flip_charJiri Slaby1-1/+1
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.

Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty pointer in many call sites.

2013-01-15synclink fix ldisc buffer argumentPaul Fulghum1-1/+11
Fix call to line discipline receive_buf by synclink drivers. Dummy flag buffer argument is ignored by N_HDLC line discipline but might be of insufficient size if accessed by a different line discipline selected by mistake. flag buffer allocation now matches max size of data buffer. Unused char_buf buffers are removed. Signed-off-by: Paul Fulghum <paulkf@microgate.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-11-15TTY: call tty_port_destroy in the rest of driversJiri Slaby1-1/+4
After commit "TTY: move tty buffers to tty_port", the tty buffers are not freed in some drivers. This is because tty_port_destructor is not called whenever a tty_port is freed. This was an assumption I counted with but was unfortunately untrue. So fix the drivers to fulfil this assumption. To be sure, the TTY buffers (and later some stuff) are gone along with the tty_port, we have to call tty_port_destroy at tear-down places. This is mostly where the structure containing a tty_port is freed. This patch does exactly that -- put tty_port_destroy at those places.

2012-09-26pcmcia: synclink_cs: fix potential tty NULL dereferenceAlexey Khoroshilov1-7/+13
tty_port_tty_get() can return NULL after port hangup that may happen anytime. The patch adds checks that tty_port_tty_get() returns nonNULL around places where tty is actually used. I have no actual hardware to test the patch, so I have updated rx side processing from common sense only. v2: rx handling updated according Alan Cox feedback.

2012-08-13TTY: synclink_cs, use dynamic tty devicesJiri Slaby1-12/+15
This allows us to provide the tty layer with information about tty_port for each link. And it also allows us to get rid of the remove_device loop in synclink_cs_exit because we had to reorder pcmcia and tty driver registration in init. This was because we need to have serial_driver initialized when calling tty_port_register_device from pcmcia ->probe.

2012-08-13TTY: synclink_cs, sanitize fail pathsJiri Slaby1-27/+14
We will need to change the order of tty and pcmcia drivers initializations (see the reason later in this series). And the fail path handling is currently performed in a separate function that as well takes care of proper deinitialization in module_exit. It is hard to read and will need to be adjusted by our changes anyway. Instead, get rid of this helper function and do the fail paths handling directly in the init function.

2012-03-08TTY: remove unneeded tty->index checksJiri Slaby1-1/+1
Checking if tty->index is in bounds is not needed. The tty has the index set in the initial open. This is done in get_tty_driver. And it can be only in interval <0,driver->num).

Use the IRQ from *p_dev->irq. - use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will clean up automatically on calls to pcmcia_disable_device() or device ejection. - drivers still not capable of IRQF_SHARED (or not telling us so) may use the deprecated pcmcia_request_exclusive_irq() for the time being; they might receive a shared IRQ nonetheless.

2009-11-28pcmcia: rework the irq_req_t typedefDominik Brodowski1-3/+0
Most of the irq_req_t typedef'd struct can be re-worked quite easily: (1) IRQInfo2 was unused in any case, so drop it. (2) IRQInfo1 was used write-only, so drop it. (3) Instance (private data to be passed to the IRQ handler): Most PCMCIA drivers using pcmcia_request_irq() to actually register an IRQ handler set the "dev_id" to the same pointer as the "priv" pointer in struct pcmcia_device. Modify the two exceptions (ipwireless, ibmtr_cs) to also work this waym and set the IRQ handler's "dev_id" to p_dev->priv unconditionally. (4) Handler is to be of type irq_handler_t. (5) Handler != NULL already tells whether an IRQ handler is present. Therefore, we do not need the IRQ_HANDLER_PRESENT flag in irq_req_t.Attributes.

2009-11-09pcmcia: use dynamic debug infrastructure, deprecate CS_CHECK (char)Dominik Brodowski1-12/+11
Convert PCMCIA drivers to use the dynamic debug infrastructure, instead of requiring manual settings of PCMCIA_DEBUG. Only some rare extra debug checks in cm4000_cs.c cm4040_cs.c are now hidden behind a "#ifdef CM4000_DEBUG" or "#ifdef CM4040_DEBUG". Also, remove all usages of the CS_CHECK macro and replace them with proper Linux style calling and return value checking. The extra error reporting may be dropped, as the PCMCIA core already complains about any (non-driver-author) errors.

2009-11-08pcmcia: use pcmcia_loop_config in misc pcmcia driversDominik Brodowski1-40/+24
Use pcmcia_loop_config() in a few drivers missed during the first round. On fmvj18x_cs.c it -- strangely -- only requries us to set conf.ConfigIndex, which is done by the core, so include an empty loop function which returns 0 unconditionally. CC: David S.

2009-06-11tty: Add carrier processing on close to the tty_port coreAlan Cox1-4/+7
Some drivers implement this internally, others miss it out. Push the behaviour into the core code as that way everyone will do it consistently. Update the dtr rts method to raise or lower depending upon flags. Having a single method in this style fits most of the implementations more cleanly than two funtions.
