2008-10-17USB: EHCI, OHCI, UHCI: remove version numbersAlan Stern
This patch (as1145) removes the essentially useless driver-version strings from ehci-hcd, ohci-hcd, and uhci-hcd. It also unifies the form of the banner lines they display upon loading and adds a missing test for usb_disabled() to ehci-hcd.

2008-10-17USB: ftdi-elan: Always pass usb_bulk_msg() a timeout in milliseconds.Sarah Sharp
The kernel doc for usb_bulk_msg() says the timeout for a bulk message should be specified in milliseconds. The ftdi-elan driver converts milliseconds to jiffies before passing the timeout to usb_bulk_msg(). This is mostly harmless, since it will just lead to very long timeouts, but was obviously not the intent of the original author.

2008-10-17USB: isp1760: Use an IS_ERR test rather than a NULL testJulien Brunel
In case of error, the function isp1760_register returns an ERR pointer, but never returns a NULL pointer. So after a call to this function, a NULL test should be replaced by an IS_ERR test. Moreover, we have noticed that: (1) the result of isp1760_register is assigned through the function pci_set_drvdata without an error test, (2) if the call to isp1760_register fails, the current function (isp1761_pci_probe) returns 0, and if it succeeds, it returns -ENOMEM, which seems odd. Thus, we suggest to move the test before the call to pci_set_drvdata to correct (1), and to turn it into a non IS_ERR test to correct (2). The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @bad_null_test@ expression x,E; statement S1, S2; @@ x = isp1760_register(...) ... when != x = E * if (x == NULL) S1 else S2 // </smpl> Signed-off-by: Julien Brunel <brunel@diku.dk> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-10-17USB: improve ehci_watchdog's side effect in CPU power managementYi Yang
ehci_watchdog will wake up CPU very frequently so that CPU stays at C3 very short, average residence time is about 50 ms on Aspire One, but we expect it should be about 1 second or more, so this kind of periodic timer is very bad for power saving. We can't remove this timer because of some bad USB controller chipset, but at least we should reduce its side effect to as possible as low. This patch can make CPU stay at C3 longer, average residence time is about twice as long as original.

2008-10-17USB: UHCI: improve scheduling of interrupt URBsAlan Stern
This patch (as1140) adds a little intelligence to the interrupt-URB scheduler in uhci-hcd. Right now the scheduler is stupid; every URB having the same period is assigned to the same slot. Thus a large group of period-N URBs can fill their slot and cause -ENOSPC errors even when all the lower-period slots are empty. With the patch, if an URB doesn't fit in its assigned slot then the scheduler will try using lower-period slots. This will provide greater flexibility. As an example, the driver will be able to handle more than just three or four mice, which the current driver cannot.

2008-10-17usb gadget: cdc ethernet notification bugfixDavid Brownell
Bugfix for the new CDC Ethernet code: as part of activating the network interface's USB link, make sure its link management code knows whether the interface is open or not. Without this fix, the link won't work right when it's brought up before the link is active ... because the initial notification it sends will have the wrong link state (down, not up).

2008-10-17usbmon: fix tiny race exposed by the fastboot patchesArjan van de Ven
usbmon registers the notifier chain, takes the bus lock and then goes to scan the existing devices for hooking up. Unfortunately, if usb_mon gets initialized while USB bus discovery is going on, it's possible that usbmon gets a notifier on one cpu (which runs without USB locks), and the scan is going on and also finds the new bus, resulting in a double sysfs registration, which then produces a WARNING.

2008-10-17USB: change hub initialization sleeps to delayed_workAlan Stern
This patch (as1137) changes the hub_activate() routine, replacing the power-power-up and debounce delays with delayed_work calls. The idea is that on systems where the USB stack is compiled into the kernel rather than built as modules, these delays will no longer block the boot thread. At least 100 ms is saved for each root hub, which can add up to a significant savings in total boot time. Arjan van de Ven was very pleased to see that this shaved 700 ms off his computer's boot time. Since his total boot time is on the order of two seconds, the improvement is considerable.

2008-10-17USB: ehci-dbg: increase debug buffer size for periodic fileMing Lei
This patch is based on the following ideas: 1.

For example, 4KB buffer is not enough for a single interrupt qh of 2ms period. 2. print a %p need 16 byte buffer on 64-bits arch, but 8 byte on 32-bits arch. Add a extra bonus for 64-bits arch.

2008-10-17OHCI: Allow broken controllers to auto-stopAlan Stern
This patch (as1134) attempts to improve the way we handle OHCI controllers with broken Root Hub Status Change interrupt support. In these controllers the RHSC interrupt bit essentially never turns off, making RHSC interrupts useless -- they have to remain permanently disabled. Such controllers should still be allowed to turn off their root hubs when no devices are attached. Polling for new connections can continue while the root hub is suspended. The patch implements this feature. (It won't have much effect unless CONFIG_PM is enabled and CONFIG_USB_SUSPEND is disabled, but since the overhead is very small we may as well do it.)

2008-10-17usb-storage: report underflow with no sense dataAlan Stern
This patch (as1118) addresses a problem with certain USB mass-storage devices. These devices sometimes return less data than asked for and then provide no sense data to explain the problem. Currently usb-storage leaves it up to the SCSI layer to decide how this should be handled, and the SCSI layer interprets the lack of sense data to mean that nothing went wrong. But if we got less data than required then something definitely _did_ go wrong, and we should say so. The patch tells the SCSI layer to retry the command when this sort of thing happens. Retrying may not solve the underlying problem, but it's better than believing that data was transferred when it wasn't.

It spares people writing support for specific boards the burden to configure the interrupt controller independantly, and keeps all IRQ related information in a single resource.
