2016-02-04xhci: harden xhci_find_next_ext_cap against device removalJoe Lawrence
xhci_find_next_ext_cap doesn't check for PCI hotplug removal and may use the PCI master abort bit pattern (~0) to calculate a new PCI address offset to read/write. The has lead to reproducable crashes when testing surprise removal during device initialization on a Stratus platform, at least after commit d5ddcdf4d672 ("xhci: rework xhci extended capability list parsing functions"). The crash is repeatable on a Stratus platform when injecting hardware faults to induce xHCI host controller hotplug during driver initialization. If a PCI read in xhci_find_next_ext_cap returns the master abort pattern, quirk_usb_handoff_xhci may start using a bogus ext_cap_offset to start searching more bogus PCI addresses.

2016-02-04ARM: nomadik: fix up SD/MMC DT settingsLinus Walleij
The DTSI file for the Nomadik does not properly specify how the PL180 levelshifter is connected: the Nomadik actually needs all the five st,sig-dir-* flags set to properly control all lines out. Further this board supports full power cycling of the card, and since this variant has no hardware clock gating, it needs a ridiculously low frequency setting to keep up with the ever overflowing FIFO. The pin configuration set-up is a bit of a mystery, because of course these pins are a mix of inputs and outputs. However the reference implementation sets all pins to "output" with unspecified initial value, so let's do that here as well.

2016-02-04ALSA: timer: Fix leftover link at closingTakashi Iwai
In ALSA timer core, the active timer instance is managed in active_list linked list. Each element is added / removed dynamically at timer start, stop and in timer interrupt. The problem is that snd_timer_interrupt() has a thinko and leaves the element in active_list when it's the last opened element. This eventually leads to list corruption or use-after-free error. This hasn't been revealed because we used to delete the list forcibly in snd_timer_stop() in the past. However, the recent fix avoids the double-stop behavior (in commit [f784beb75ce8: ALSA: timer: Fix link corruption due to double start or stop]), and this leak hits reality. This patch fixes the link management in snd_timer_interrupt(). Now it simply unlinks no matter which stream is.

changeset 70433a152f0 ("media: videobuf2: Refactor vb2_fileio_data and vb2_thread") broke videobuf2-dvb.

2016-02-04[media] vb2: fix nasty vb2_thread regressionHans Verkuil
The vb2_thread implementation was made generic and was moved from videobuf2-v4l2.c to videobuf2-core.c in commit af3bac1a. Unfortunately that clearly was never tested since it broke read() causing NULL address references. The root cause was confused handling of vb2_buffer vs v4l2_buffer (the pb pointer in various core functions). The v4l2_buffer no longer exists after moving the code into the core and it is no longer needed. However, the vb2_thread code passed a pointer to a vb2_buffer to the core functions were a v4l2_buffer pointer was expected and vb2_thread expected that the vb2_buffer fields would be filled in correctly. This is obviously wrong since v4l2_buffer != vb2_buffer. Note that the pb pointer is a void pointer, so no type-checking took place. This patch fixes this problem: 1) allow pb to be NULL for vb2_core_(d)qbuf. The vb2_thread code will use a NULL pointer here since they don't care about v4l2_buffer anyway. 2) let vb2_core_dqbuf pass back the index of the received buffer. This is all vb2_thread needs: this index is the index into the q->bufs array and vb2_thread just gets the vb2_buffer from there. 3) the fileio->b pointer (that originally contained a v4l2_buffer) is removed altogether since it is no longer needed.

2016-02-03usb: xhci: set SSIC port unused only if xhci_suspend succeedsLu Baolu
XHCI_SSIC_PORT_UNUSED quirk was applied to the xHCI host controllers in some Intel SoC chips. With this quirk applied, SSIC port is set to "unused" prior to xhci_suspend(). This may cause problem if host fails to suspend. In this case, the port is set to unused without host further entering D3, and the port will not be usable anymore.

2016-02-03usb: xhci: add a quirk bit for ssic port unusedLu Baolu
Two workarounds introduced by commit b8cb91e058cd ("xhci: Workaround for PME stuck issues in Intel xhci") and commit abce329c27b3 ("xhci: Workaround to get D3 working in Intel xHCI") share a single quirk bit XHCI_PME_STUCK_QUIRK. These two workarounds actually are different and might happen on different hardwares. Need to separate them by adding a quirk bit for the later.

2016-02-03usb: xhci: handle both SSIC ports in PME stuck quirkLu Baolu
Commit abce329c27b3 ("xhci: Workaround to get D3 working in Intel xHCI") adds a workaround for a limitation of PME storm caused by SSIC port in some Intel SoCs. This commit only handled one SSIC port, while there are actually two SSIC ports in the chips. This patch handles both SSIC ports. Without this fix, users still see PME storm.

2016-02-03usb: dwc3: gadget: set the OTG flag in dwc3 gadget driver.Jianqiang Tang
This patch is needed in order to pass one test case defined in the OTG Automated Compliance Test specification. Specification location: http://www.usb.org/developers/onthego/otgeh_compliance_plan_1_2.pdf This test case uses PET Tool, and PET Tool is one USB hardware equipment provided by MQP Electronics. Test case id is 6.8.3 B-UUT Bypass Capacitance. We must set this otg flag in order to be able to return OTG descriptor during enumeration, otherwise this test case with failed with below error: "Get OTG descriptor request stalled".

2016-02-03Revert "xhci: don't finish a TD if we get a short-transfer event mid TD"Mathias Nyman
This reverts commit e210c422b6fd ("xhci: don't finish a TD if we get a short transfer event mid TD") Turns out that most host controllers do not follow the xHCI specs and never send the second event for the last TRB in the TD if there was a short event mid-TD. Returning the URB directly after the first short-transfer event is far better than never returning the URB. (class drivers usually timeout after 30sec). For the hosts that do send the second event we will go back to treating it as misplaced event and print an error message for it. The origial patch was sent to stable kernels and needs to be reverted from there as well Cc: stable@vger.kernel.org Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This reverts commit 263b7fb557f7 ("usb: dwc2: Move reset into dwc2_get_hwparams()") due to regression found on bcm2835 platform.

2016-02-03PM: Avoid false-positive warnings in dev_pm_domain_set()Rafael J. Wysocki
There is a WARN_ON() in dev_pm_domain_set() that triggers on attempts to set the pm_domain pointer for devices with a driver bound. However, that WARN_ON() triggers on attempts to clear the pointer too and the test it uses is based on checking the device's p->knode_driver pointer which still is set when the device bus type's/driver's ->remove callback has been executed. This leads to false-positive warnings when bus type code calls dev_pm_domain_set() to clear the pm_domain pointer after invoking the driver's ->remove() callback. To avoid those false-positives, make dev_pm_domain_set() check if the pointer passed to it is NULL and skip the warning in that case.
