      dmaengine: add possibility for cyclic transfers · 782bc950
      Sascha Hauer 提交于
      Cyclic transfers are useful for audio where a single buffer divided
      in periods has to be transfered endlessly until stopped. After being
      prepared the transfer is started using the dma_async_descriptor->tx_submit
      function. dma_async_descriptor->callback is called after each period.
      The transfer is stopped using the DMA_TERMINATE_ALL callback.
      While being used for cyclic transfers the channel cannot be used
      for other transfer types.

      Staging: vt6655: fix buffer overflow · dd173abf
      Dan Carpenter 提交于
      "param->u.wpa_associate.wpa_ie_len" comes from the user.  We should
      check it so that the copy_from_user() doesn't overflow the buffer.
      
      Also further down in the function, we assume that if
      "param->u.wpa_associate.wpa_ie_len" is set then "abyWPAIE[0]" is
      initialized.  To make that work, I changed the test here to say that if
      "wpa_ie_len" is set then "wpa_ie" has to be a valid pointer or we return
      -EINVAL.
      
      Oddly, we only use the first element of the abyWPAIE[] array.  So I
      suspect there may be some other issues in this function.

      Revert: "Staging: batman-adv: Adding netfilter-bridge hooks" · 350aede6
      Sven Eckelmann 提交于
      This reverts commit 96d592ed.
      
      The netfilter hook seems to be misused and may leak skbs in situations
      when NF_HOOK returns NF_STOLEN. It may not filter everything as
      expected. Also the ethernet bridge tables are not yet capable to
      understand batman-adv packet correctly.
      
      It was only added for testing purposes and can be removed again.

      USB: serial/mos*: prevent reading uninitialized stack memory · a0846f18
      Dan Rosenberg 提交于
      The TIOCGICOUNT device ioctl in both mos7720.c and mos7840.c allows
      unprivileged users to read uninitialized stack memory, because the
      "reserved" member of the serial_icounter_struct struct declared on the
      stack is not altered or zeroed before being copied back to the user.
      This patch takes care of it.

      USB: otg: twl4030: fix phy initialization(v1) · fc8f2a76
      Ming Lei 提交于
      Commit 461c3177(into 2.6.36-v3)
      is put forward to power down phy if no usb cable is connected,
      but does introduce the two issues below:
      
      1), phy is not into work state if usb cable is connected
      with PC during poweron, so musb device mode is not usable
      in such case, follows the reasons:
      	-twl4030_phy_resume is not called, so
      		regulators are not enabled
      		i2c access are not enabled
      		usb mode not configurated
      
      2), The kernel warings[1] of regulators 'unbalanced disables'
      is caused if poweron without usb cable connected
      with PC or b-device.
      
      This patch fixes the two issues above:
      	-power down phy only if no usb cable is connected with PC
      and b-device
      	-do phy initialization(via __twl4030_phy_resume) if usb cable
      is connected with PC(vbus event) or another b-device(ID event) in
      twl4030_usb_probe.
      
      This patch also doesn't put VUSB3V1 LDO into active mode in
      twl4030_usb_ldo_init until VBUS/ID change detected, so we can
      save more power consumption than before.
      
      This patch is verified OK on Beagle board either connected with
      usb cable or not when poweron.
      
      [1]. warnings of 'unbalanced disables' of regulators.

      This patch forces the use of the legacy pll algo on RV620
      LVDS panels.  The old behavior (new pll algo) can be selected
      by setting the new_pll module parameter to 1.

      drm: fix race between driver loading and userspace open. · b64c115e
      Dave Airlie 提交于
      Not 100% sure this is due to BKL removal, its most likely a combination
      of that + userspace timing changes in udev/plymouth. The drm adds the sysfs
      device before the driver has completed internal loading, this causes udev
      to make the node and plymouth to open it before we've completed loading.
      
      The proper solution is to delay the sysfs manipulation until later in loading
      however this causes knock on issues with sysfs connector nodes, so we can use
      the global mutex to serialise loading and userspace opens.

      The device is associated with the usbhid driver, so let's do
      usb_find_interface(&hid_driver) instead.
      
      $ ls -l /sys/devices/pci0000:00/0000:00:1d.2/usb7/7-1/7-1:1.0/usb/hiddev0/device/driver

      ide: Fix ordering of procfs registry. · dbee0322
      Wolfram Sang 提交于
      We must ensure that ide_proc_port_register_devices() occurs on an
      interface before ide_proc_register_driver() executes for that
      interfaces drives.
      
      Therefore defer the registry of the driver device objects backed by
      ide_bus_type until after ide_proc_port_register_devices() has run
      and thus all of the drive->proc procfs directory pointers have been
      setup.
