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:

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:

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).

Change the module parameters rcv_buf_size and snd_buf_size to specify buffer sizes in bytes rather than ATM cells. Since there is some danger that users may not notice this change, the parameters are renamed to rcv_buf_bytes etc. The transmit buffer needs to be a multiple of the ATM cell size in length, while the receive buffer should be a multiple of the endpoint maxpacket size (this wasn't enforced before, which causes trouble with isochronous transfers), so enforce these restrictions. Now that the usbatm probe method inspects the endpoint maxpacket size, minidriver bind routines need to set the correct alternate setting for the interface in their bind routine. This is the reason for the speedtch changes. Signed-off-by:

In one spot (usbatm_cancel_send) we were calling dev_kfree_skb with irqs disabled. This mistake is just too easy to make, so systematically use dev_kfree_skb_any rather than dev_kfree_skb. Signed-off-by:

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:

The xusbatm driver is for otherwise unsupported modems. All it does is grab hold of a user-specified set of interfaces - the generic usbatm core methods (hopefully) do the rest. As Aurelio Arroyo discovered when he tried to use xusbatm (big mistake!), the interface grabbing logic was completely borked. Here is a rewrite that works. Signed-off-by:

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. Signed-off-by:

This should fix things mentioned below: "I was curious why my firewall was loading a 'phone driver'. It turns out that the probing in the yealink driver is a little too assuming.. static struct usb_device_id usb_table [] = { { USB_INTERFACE_INFO(USB_CLASS_HID, 0, 0) }, { } }; So it picked up my UPS, and loaded the driver. Whilst no harm came, because it later checks the vendor/product IDs, this driver should probably be rewritten to only probe for the device IDs it actually knows about.

Documentation: Specify grayscale specification on ATIK-ATK16 and ATIK-ATK16HR comments. New: Add ProductID and VendorID for devices ATIK-ATK16C and ATIK-ATK16HRC. These devices are also USB Astronomical CCD cameras that work through an FTDI 245BM chip, share the same base hardware but, it has a colour CCD chip instead of a grayscale one. Signed-off-by:

For crying out loud, they have devices which do not like port resets. So, do what usb-storage does and try both bulk and port resets. We start with a port reset (which usb-storage does at the end of transport), then do a Bulk reset, then a port reset again. This seems to work for me. The code is getting dirtier and dirtier here, but I swear that I'll do something about it (see those two new XXX). Honest. Signed-off-by:

If SCSI commands are submitted while other commands are still processed, the dispatch loop turns, and we stop the work_timer. Then, if URB fails to complete, ub hangs until the device is unplugged. This does not happen often, becase we only allow one SCSI command per block device, but does happen (on multi-LUN devices, for example). The fix is to stop timer only when we actually going to change the state. The nicest code would be to have the timer stopped in URB callback, but this is impossible, because it can be called from inside a timer, through the urb_unlink. Then we get BUG in timer.c:cascade(). So, we do it a little dirtier. Signed-off-by:

The blk_cleanup_queue does not necesserily destroy the queue. When we destroy the corresponding ub_dev, it may leave the queue spinlock pointer dangling. This patch moves spinlocks from ub_dev to static memory. The locking scheme is not changed. These spinlocks are still separate from the ub_lock. Signed-off-by:

This moves the previously widely-used ehci-pci.c BIOS handoff code into the pci-quirks.c file, replacing the less widely used "early handoff" version that seems to cause problems lately. One notable change: the "early handoff" version always enabled an SMI IRQ ... and did so even if the pre-Linux code said it was not using EHCI (and not expecting EHCI SMIs). Looks like a goof in a workaround for some unknown BIOS version. This merged version only forcibly enables those IRQs when pre-Linux code says it's using EHCI. And now it always forces them off "just in case". Signed-off-by:
