keyspan: fix oops

2008-01-22T03:39:41Z

If we get a data URB back from the hardware after we have put the tty to bed we go kaboom. Fortunately all we need to do is process the URB without trying to ram its contents down the throat of an ex-tty.

pl2303: Fix mode switching regression

2008-01-09T00:16:34Z

Cleaning out all the incorrect 'no change made' checks for termios settings showed up a problem with the PL2303. The hardware here seems to lose sync and bits if you tell it to make no changes. This shows up with a real world application. To fix this the driver check for meaningful hardware changes is restored but doing the tests correctly and as a tty layer function so it doesn't get duplicated wrongly everywhere if other drivers turn out to need it.

USB: New device ID for the CP2101 driver

2007-12-23T07:14:33Z

attached please find a new device ID for CP2101 driver. This device is a usb stick from Dynastream to communicate with ANT wireless devices which I suppose is fairly similar to the ANT dev board having product id 0x1003. From: Martin Kusserow Signed-off-by: Greg Kroah-Hartman

USB: VID/PID update for sierra

2007-12-23T07:14:33Z

Adds VID/PID for the MC8775 found internally in the Thinkpad X61s laptop (and likely others). For commercial reasons the driver maintainer cannot add VID/PIDs for laptop OEM devices himself. Signed-off-by: Kevin R Page Cc: stable Signed-off-by: Greg Kroah-Hartman

USB: Unbreak fsl_usb2_udc

2007-12-23T07:14:33Z

Commit a4e3ef5... (USB: gadget: gadget_is_{dualspeed,otg} predicates and cleanup) broke fsl_usb2_udc; the build test didn't cover peripheral drivers, just gadget drivers. Signed-off-by: Peter Korsgaard Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman

USB: revert portions of "UNUSUAL_DEV: Sync up some reported devices from Ubuntu"

2007-12-17T18:47:16Z

This reverts one change from 67fa10627ec0d8aa16f1cf38cf527e67d8097d3c that prevented userspace from seing the "driver disk" lun in a san disk device. The kernel shouldn't do this, it's up to userspace to handle this properly, if it somehow wants to filter this away.

usb: Remove broken optimisation in OHCI IRQ handler

2007-12-17T18:47:15Z

The OHCI IRQ handler has an optimisation that avoids reading some chip registers when the controller reports that the interrupt was triggered *only* because completed requests were written into the controller's "done list" and handed to the host. This mechanism can't be used on some controllers. Among others, it fails for the SA1111 and the AMCC 440EP PowerPC processor. This patch removes the optimisation and makes the code clearer.

USB: at91_udc: correct hanging while disconnecting usb cable

2007-12-17T18:47:15Z

Correct hanging while disconnecting the USB device cable. Prevent a race between vbus and UDP interrupts. This bug was tracked on at91sam9260ek boards. A usb resume interrupt was firing after the vbus interrupt : the IP was then already stoped and not able to deal with it (no more clock). A simple interrupt disabling is ok as the "end of bus reset" irq is non maskable and ok to resume the USB device IP.

USB: use IRQF_DISABLED for HCD interrupt handlers

2007-12-17T18:47:15Z

Host controller IRQs are supposed to be serviced with interrupts disabled. This patch (as1026) adds an IRQF_DISABLED flag to all the controller drivers that lack it. It also replaces the spin_lock_irqsave() and spin_unlock_irqrestore() calls in uhci_irq() with simple spin_lock() and spin_unlock(). This fixes Bugzilla #9335.

USB: fix locking loop by avoiding flush_scheduled_work

2007-12-17T18:47:15Z

This patch (as1027) replaces a call to flush_scheduled_work() -- a dangerous routine to invoke, especially while holding any sort of lock -- with calls to cancel_work_sync() and cancel_delayed_work_sync(). This fixes Bugzilla #9532. Signed-off-by: Alan Stern CC: David Brownell Signed-off-by: Greg Kroah-Hartman
