If either the driver's open() method or try_module_get() fails, we need to set 'tty->driver_data' and 'port->tty' to NULL in serial_open(), otherwise we'll get an OOPS in usb_device_disconnect() when the device is disconnected.

This is a new driver for the Cypress CY7C63xxx mirco controller series. It currently supports the pre-programmed CYC63001A-PC by AK Modul-Bus GmbH. It's based on a kernel 2.4 driver (cyport) by Marcus Maul which I ported to kernel 2.6 using sysfs. I intend to support more controllers of this family (and more features) as soon as I get hold of the required IDs etc. Please see the source code's header for more information.

This update contains one bug fix: some lines can come out truncated, because of the safety cutoff. This happened because I forgot to update the size when status packets began to be printed. The rest is: - Comments updates - Allow snooping with pkmap on x86_64, which is cache-coherent - Enlarge event buffers (certainly we can have a couple of pages) - Add event counter First touch upon usbmon for 2.6.18.

This patch (as707) improves the FSBR operation in uhci-hcd by turning it off more quickly when it isn't needed. FSBR puts a noticeable load on a computer's PCI bus, so it should be disabled as soon as possible when it isn't in use. The patch leaves it running for only 10 ms after the last URB stops using it, on the theory that this should be long enough for a driver to submit another URB if it wants keep FSBR going.

This patch (as706) removes the private hc_inaccessible flag from uhci-hcd. It's not needed because it conveys exactly the same information as the generic HCD_FLAG_HW_ACCESSIBLE bit. In its place goes a new flag recording whether the controller is dead. The new code allows a complete device reset to resurrect a dead controller (although usbcore doesn't yet implement such a facility).

This patch (as705) contains a small set of updates for uhci-hcd written mostly by Dave Brownell: * Root hub suspend messages come out labeled as root hub messages; PCI messages should only come out when the pci device suspends. * Rename the reset() method to better match its init() role * Behave more like the other HCDs by returning -ESHUTDOWN for root-hub suspend/resume errors. * When an URB fails, associate the message with the usb device not the host controller (it still hides endpoint and direction) From: David Brownell <david-b@pacbell.net> Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

This patch (as703) improves the error handling when a Set-Configuration request fails. The old interfaces are all unregistered before the request is sent, and if the request fails then we don't know what config the device is using. So it makes no sense to leave actconfig pointing to the old configuration with its invalid interfaces.

This patch (as700) modifies the hub driver to take advantage of the new usb_reset_composite_device API. The existing code had special-case calls stuck into usb_reset_device, just before and after the reset. With the new version there's no need for special-case stuff; it all happens naturally in the form of pre_reset and post_reset notifications.

This patch (as699) adds usb_reset_composite_device(), a routine for sending a USB port reset to a device with multiple interfaces owned by different drivers. Drivers are notified about impending and completed resets through two new methods in the usb_driver structure. The patch modifieds the usbfs ioctl code to make it use the new routine instead of usb_reset_device(). Follow-up patches will modify the hub, usb-storage, and usbhid drivers so they can utilize this new API.

From: Eric Sesterhenn <snakebyte@gmx.de> This fixes coverity Bug #390. With the following code ret = ep->branch = balance(isp116x, ep->period, ep->load); if (ret < 0) goto fail; the problem is that ret and balance are of the type int, and ep->branch is u16. so the int balance() returns gets reduced to u16 and then converted to an int again, which removes the sign. Maybe the following little c program can explain it better:

2.6.16 introduces USB power budgeting in the Linux kernel, and since then, a fair number of users have observed that some of their devices no longer work in unpowered hubs (this is not a bug, the devices claim that they need more than 100mA). The very least we can do is print an informational message to the kernel log when this happens, otherwise it is not at all clear why the device was not accepted.

<zaitcev> I am taling about this: "if (disk->flags & GENHD_FL_UP) del_gendisk(disk);" <zaitcev> If del_gendisk() undoes add_disk() like viro just said, why is it conditional? <viro> huh? <viro> add_disk() sets the damn flag <zaitcev> So, I should not need to check ever <viro> so the above is "if I've called add_disk(), call gendisk()" <viro> which might be what you want, of course <viro> but usually you know if you'd done add_disk() on that puppy anyway In ub, nobody upstream should ever see half-constructed disks before they were passed to add_disk. To that end, only add the struct lun to the list on the path of no return. With that fix in place, we do not need to test GENHD_FL_UP.

Dan Streetman authored
This updates the EHCI driver by adding an improved scheduler for the transaction translators, found in USB 2.0 hubs and used for low and full speed devices. - adds periodic_tt_usecs() and some helper functions, which does the same thing that "periodic_usecs" does, except on the other side of the TT, i.e. it calculates the low/fullspeed bandwidth usage instead of highspeed. - adds a tt_available() function which is the new implementation of what tt_no_collision() does ... while tt_no_collision() ensures that each TT handles only 1 periodic transfer at a time (a very pessimistic approach) this version instead tracks bandwidth and allows each TT to handle as many transfers as will fit on each TT's downstream bus (closer to best-case). The new scheduler is selected by a config option, marked as EXPERIMENTAL so it can be tested (and more broadly reviewed) for a while until it seems safe to remove the original scheduler.
