2012-03-15rt2x00: rt2800usb: do not check packedid for aggregated framesStanislaw Gruszka
Tx statuses of aggregated subframes contain packetid of first subframe in the AMPDU. We can not identify AMPDU subframes based on packedid, so simply assume that status match first pending frame in the queue. Thats mostly the same what 2800pci do.

2012-03-15rt2x00: rt2800usb: rework txstatus codeStanislaw Gruszka
Currently we read tx status register after each urb data transfer. As callback procedure also trigger reading, that causing we have many "threads" of reading status. To prevent that introduce TX_STATUS_READING flags, and check if we are already in process of sequential reading TX_STA_FIFO, before requesting new reads. Change timer to hrtimer, that make TX_STA_FIFO overruns less possible. Use 200 us for initial timeout, and then reschedule in 100 us period, this values probably have to be tuned. Make changes on txdone work. Schedule it from rt2800usb_tx_sta_fifo_read_completed() callback when first valid status show up. Check in callback if tx status timeout happens, and schedule work on that condition too. That make possible to remove tx status timeout from generic watchdog. I moved that to rt2800usb. Loop in txdone work, that should prevent situation when we queue work, which is already processed, and after finish work is not rescheduled again.

2012-03-15rt2x00: rt2800usb: rework txdone codeStanislaw Gruszka
Patch change txdone code to make it similar like txdone in rt2800pci, process only one entry from queue matching tx status. Before we processed all pending entries from queue until PACKEDID match, that caused that we do not report tx statuses correctly.

2012-03-15i2c-algo-bit: Fix spurious SCL timeouts under heavy loadVille Syrjala
When the system is under heavy load, there can be a significant delay between the getscl() and time_after() calls inside sclhi(). That delay may cause the time_after() check to trigger after SCL has gone high, causing sclhi() to return -ETIMEDOUT. To fix the problem, double check that SCL is still low after the timeout has been reached, before deciding to return -ETIMEDOUT.

2012-03-15drm/udl: initial UDL driver (v4)Dave Airlie
This is an initial drm/kms driver for the displaylink devices. Supports fb_defio, supports KMS dumb interface supports 24bpp via conversion to 16bpp, hw can do this better. supports hot unplug using new drm core features. On an unplug, it disables connector polling, unplugs connectors from sysfs, unplugs fbdev layer (using Kay's API), drops all the USB device URBs, and call the drm core to unplug the device. This driver is based in large parts on udlfb.c so I've licensed it under GPLv2. Signed-off-by: Dave Airlie <airlied@redhat.com>

The second adds an unplugged state, if we have device opens, we just set the unplugged state and return, if we have no device opens we drop the drm device.

2012-03-15udlfb: remove sysfs framebuffer device with USB .disconnect()Kay Sievers
The USB graphics card driver delays the unregistering of the framebuffer device to a workqueue, which breaks the userspace visible remove uevent sequence. Recent userspace tools started to support USB graphics card hotplug out-of-the-box and rely on proper events sent by the kernel. The framebuffer device is a direct child of the USB interface which is removed immediately after the USB .disconnect() callback. But the fb device in /sys stays around until its final cleanup, at a time where all the parent devices have been removed already. To work around that, we remove the sysfs fb device directly in the USB .disconnect() callback and leave only the cleanup of the internal fb data to the delayed work. Before: add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb0 (graphics) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) remove /2-1.2:1.0/graphics/fb0 (graphics) After: add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) Cc: stable@vger.kernel.org Tested-by: Bernie Thompson <bernie@plugable.com> Acked-by: Bernie Thompson <bernie@plugable.com> Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
