* usbatm: Fix dynamic_debug / ratelimited atm_dbg and atm_rldbg macrosJoe Perches2013-10-291-7/+7
| | | | | | | | | Fix atm_dbg to use normal pr_debug not dynamic_pr_debug because dynamic_pr_debug may not be compiled in at all. Signed-off-by: Joe Perches <joe@perches.com> Tested-by: Krzysztof Mazur <krzysiek@podlesie.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* USB: usbatm: move the atm_dbg() call to use dynamic debugGreg Kroah-Hartman2013-07-231-11/+5
| | | | | | | | | | | | Move the atm_dbg() call to use the dynamic debug subsystem, and not rely on CONFIG_USB_DEBUG for if things should be printed out or not. This also means the drivers do not have to be rebuilt to get debugging messages, important for getting information from users who can not rebuild their kernels.

* USB: usbatm: don't rely on CONFIG_USB_DEBUGGreg Kroah-Hartman2013-07-231-6/+1
| | | | | | | | | | | | | | | Enable the USB atm drivers to use the dynamic debugging subsystem, and not rely on if CONFIG_USB_DEBUG is enabled or not for debugging messages. This also provides a saner debug message, pointing out the exact device the message is coming from. This also means the drivers do not have to be rebuilt to get debugging messages, important for getting information from users who can not rebuild their kernels.

* USB: usbatm: remove unused UDSL_ASSERT macroGreg Kroah-Hartman2013-07-231-12/+0
| | | | | | | | | If this code isn't triggering this assert by now, it never will, so just remove it, it's pointless. Cc: Duncan Sands <duncan.sands@free.fr> Acked-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* USB: cxacru: check device isn't being removed during sysfs callsSimon Arlott2010-03-021-0/+15
| | | | | | | | | | | | | | | | | It is possible for usb_get_intfdata() to return NULL if sysfs is accessed while the module is being unloaded or the device is being removed. Move the access code to an inline function in usbatm.h, and return -ENODEV if any of the pointers are NULL. It should not be possible for the instance data or atm device to be invalid until after unbind() completes and the sysfs attributes have been removed.

* USB: remove warn() macro from usb driversGreg Kroah-Hartman2008-10-171-2/+8
| | | | | | | | | USB should not be having it's own printk macros, so remove warn() and use the system-wide standard of dev_warn() wherever possible. In the few places that will not work out, use a basic printk(). Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: usbatm: convert heavy init dances to kthread APIPavel Emelyanov2008-04-241-1/+1
| | | | | | | | | | | | | | | This is an attempt to kill two birds with one stone. First, we kill one more user of kernel_thread, which is scheduled for removal. Second - we kill one of the last users of kill_proc - the function which is also to be removed, because it uses a pid_t which is not safe now.

* drivers: Remove unnecessary inclusions of asm/semaphore.hMatthew Wilcox2008-04-181-1/+0
| | | | | | | | | None of these files use any of the functionality promised by asm/semaphore.h. It's possible that they rely on it dragging in some unrelated header file, but I can't build all these files, so we'll have fix any build failures as they come up.

* [PATCH] USBATM: -EILSEQ workaroundDuncan Sands2006-01-311-0/+1
| | | | | | | | | | Don't throttle on -EILSEQ urb status if requested by a minidriver. It seems the ueagle modems are buggy, giving -EILSEQ when they have no data to send. The ueagle change will be sent separately by the ueagle guys. Patch by Matthieu Castet. Signed-off-by: Duncan Sands <baldrick@free.fr> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] USBATM: handle urbs containing partial cellsDuncan Sands2006-01-311-0/+7
| | | | | | | | | | The receive logic has always assumed that urbs contain an integral number of ATM cells, which is a bit naughty, though it never caused any problems with bulk transfers. Isochronous urbs spank us soundly for this. Fixed thanks to this patch, mostly by Stanislaw Gruszka. Signed-off-by: Duncan Sands <baldrick@free.fr> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] USBATM: allow isochronous transferDuncan Sands2006-01-311-2/+5
| | | | | | | | | | | | | | | While the usbatm core has had some support for using isoc urbs for some time, there was no way for users to turn it on. While use of isoc transfer should still be considered experimental, it now works well enough to let users turn it on. Minidrivers signal to the core that they want to use isoc transfer by setting the new UDSL_USE_ISOC flag. The speedtch minidriver gets a new module parameter enable_isoc (defaults to false), plus some logic that checks for the existence of an isoc receive endpoint (not all speedtouch modems have one).

* [PATCH] USBATM: shutdown open connections when disconnectedDuncan Sands2006-01-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | This patch causes vcc_release_async to be applied to any open vcc's when the modem is disconnected. This signals a socket shutdown, letting the socket user know that the game is up. I wrote this patch because of reports that pppd would keep connections open forever when the modem is disconnected. This patch does not fix that problem, but it's a step in the right direction. It doesn't help because the pppoatm module doesn't yet monitor state changes on the ATM socket, so simply never realises that the ATM connection has gone down (meaning it doesn't tell the ppp layer). But at least there is a socket state change now. Unfortunately this patch may create problems for those rare users like me who use routed IP or some other non-ppp connection method that goes via the ATM ARP daemon: the daemon is buggy, and with this patch will crash when the modem is disconnected. Users with a buggy atmarpd can simply restart it after disconnecting the modem. Signed-off-by: Duncan Sands <baldrick@free.fr> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | Have minidrivers and the core signal special requirements using a flags field in struct usbatm_data. For the moment this is only used to replace the need_heavy_init bind parameter, but there'll be new flags in later patches.

* [PATCH] USB ATM: new usbatm coreDuncan Sands2005-06-271-0/+183
Rework the core usbatm code: minidrivers (i.e. drivers for particular modems) now register themselves with the usbatm core, supplying methods for binding/unbinding etc. The design was inspired by usb-serial and usbnet. At the same time, more common code from the speedtch and cxacru (patch 3/5) drivers was generalized and moved into the core. The transmission and reception parts have been unified and simplified. Since this is a major change and I don't like underscores in file names, usb_atm.[ch] has been renamed usbatm.[ch]. Many thanks to Roman Kagan, who did a lot of the coding.
