commit 9eb1fbfa upstream. Commit 1c2e0041 introduced an event handler for the encryption key refresh complete event with the intent of fixing some LE/SMP cases. However, this event is shared with BR/EDR and there we actually want to act only on the auth_complete event (which comes after the key refresh). If we do not do this we may trigger an L2CAP Connect Request too early and cause the remote side to return a security block error. Signed-off-by:

commit c1db30a2 upstream. Some OHCI controllers from ATI/AMD seem to have difficulty with "global" USB suspend, that is, suspending an entire USB bus without setting the suspend feature for each port connected to a device. When we try to resume the child devices, the controller gives timeout errors on the unsuspended ports, requiring resets, and can even cause ohci-hcd to hang; see http://marc.info/?l=linux-usb&m=139514332820398&w=2 and the following messages. This patch fixes the problem by adding a new quirk flag to ohci-hcd. The flag causes the ohci_rh_suspend() routine to suspend each unsuspended, enabled port before suspending the root hub. This effectively converts the "global" suspend to an ordinary root-hub suspend. There is no need to unsuspend these ports when the root hub is resumed, because the child devices will be resumed anyway in the course of a normal system resume ("global" suspend is never used for runtime PM). This patch should be applied to all stable kernels which include commit 0aa2832d (USB: use "global suspend" for system sleep on USB-2 buses) or a backported version thereof. Signed-off-by:

commit d183c819 upstream. Per reference manuals of Freescale P1020 and P2020 SoCs, USB controller present in these SoCs has bit 17 of USBx_CONTROL register marked as Reserved - there is no PHY_CLK_VALID bit there. Testing for this bit in ehci_fsl_setup_phy() behaves differently on two P1020RDB boards available here - on one board test passes and fsl-usb init succeeds, but on other board test fails, causing fsl-usb init to fail. This patch changes ehci_fsl_setup_phy() not to test PHY_CLK_VALID on controller version 1.6 that (per manual) does not have this bit. Signed-off-by:

commit cbfbbabb upstream. The version of the drm_tegra_submit structure that was merged all the way back in 3.10 contains a pad field that was originally intended to properly pad the following __u64 field. Unfortunately it seems like a different field was dropped during review that caused this padding to become unnecessary, but the pad field wasn't removed at that time. One possible side-effect of this is that since the __u64 following the pad is now no longer properly aligned, the compiler may (or may not) introduce padding itself, which results in no predictable ABI. Rectify this by removing the pad field so that all fields are again naturally aligned. Technically this is breaking existing userspace ABI, but given that there aren't any (released) userspace drivers that make use of this yet, the fallout should be minimal.

commit 7f1950fb upstream. Depending on the SDVO output_flags SDVO may have multiple connectors linking to the same encoder (in intel_connector->encoder->base). Only one of those connectors should be active (ie link to the encoder thru drm_connector->encoder). If intel_connector_break_all_links() is called from intel_sanitize_crtc() we may break the crtc connection of an encoder thru an inactive connector in which case intel_connector_break_all_links() will not be called again for the active connector if this happens to come later in the list due to: if (connector->encoder->base.crtc != &crtc->base) continue; in intel_sanitize_crtc(). This will however leave the drm_connector->encoder linkage for this active connector in place. Subsequently this will cause multiple warnings in intel_connector_check_state() to trigger and the driver will eventually die in drm_encoder_crtc_ok() (because of crtc == NULL). To avoid this remove intel_connector_break_all_links() and move its code to its two calling functions: intel_sanitize_crtc() and intel_sanitize_encoder(). This allows to implement the link breaking more flexibly matching the surrounding code: ie. in intel_sanitize_crtc() we can break the crtc link separatly after the links to the encoders have been broken which avoids above problem. This regression has been introduced in: commit 24929352 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Jul 2 20:28:59 2012 +0200 drm/i915: read out the modeset hw state at load and resume time so goes back to the very beginning of the modeset rework. v2: This patch takes care of the concernes voiced by Chris Wilson and Daniel Vetter that only breaking links if the drm_connector is linked to an encoder may miss some links. v3: move all encoder handling to encoder loop as suggested by Daniel Vetter.

commit 3ff04a16 upstream. The status bits are unconditionally set, the control bits only enable the actual interrupt generation. Which means if we get some random other interrupts we'll bogusly complain about them. So restrict the WARN to platforms with a sane hotplug interrupt handling scheme. And even more important also don't attempt to process the hpd bit since we've detected a storm already. Instead just clear the bit silently.

commit 9953599b upstream. ... our current modeset code isn't good enough yet to handle this. The scenario is: 1. BIOS sets up a cloned config with lvds+external screen on the same pipe, e.g. pipe B. 2. We read out that state for pipe B and assign the gmch_pfit state to it. 3. The initial modeset switches the lvds to pipe A but due to lack of atomic modeset we don't recompute the config of pipe B. -> both pipes now claim (in the sw pipe config structure) to use the gmch_pfit, which just won't work.

commit 40478455 upstream. In commit commit 6375b768 Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Mon Mar 3 11:33:36 2014 +0200 drm/i915: Reject >165MHz modes w/ DVI monitors the driver started to filter out display modes which exceed the single-link DVI 165Mz dotclock limits when the monitor doesn't report itself as being HDMI compliant. The intent was to filter out all EDID derived modes that require dual-link DVI to operate since we don't support dual-link. However the patch went a bit too far and also causes the driver to reject such modes even when specified by the user. Normally we don't check the sink limitations when setting a mode from the user. This allows the user to specify any mode whether the sink reports to support it or not. This can be useful since often the sinks support more modes than they report in the EDID. So relax the checks a bit, and apply the single-link DVI dotclock limit only when filtering the mode list, and ignore the limit when setting a user specified mode.

commit 830cbe4b upstream. Until now, we were leaving the ->check_device() msi_chip operation empty, which leads the PCI core to believe that we support both MSI and MSI-X. In fact, we do not support MSI-X, so we have to tell this to the PCI core by providing an implementation of this operation.

commit da343fc7 upstream. The armada_370_xp_alloc_msi() function returns a signed int, which is negative on error. However, we store the return value into an irq_hw_number_t, which is unsigned. Therefore, we actually never test if armada_370_xp_alloc_msi() returns an error or not, which may lead us to use hwirq numbers of as 0xffffffe4 (when armada_370_xp_alloc_msi() returns -ENOSPC). This commit fixes that by storing the return value of armada_370_xp_alloc_msi() in a signed variable. Fixes: 31f614ed ('irqchip: armada-370-xp: implement MSI support') Signed-off-by:

commit 3eba563e upstream. Address a regression caused by commit ad332c8a: (ACPI / EC: Clear stale EC events on Samsung systems) After the earlier patch, there was found to be a race condition on some earlier Samsung systems (N150/N210/N220). The function acpi_ec_clear was sometimes discarding a new EC event before its GPE was triggered by the system. In the case of these systems, this meant that the "lid open" event was not registered on resume if that was the cause of the wake, leading to problems when attempting to close the lid to suspend again. After testing on a number of Samsung systems, both those affected by the previous EC bug and those affected by the race condition, it seemed that the best course of action was to process rather than discard the events. On Samsung systems which accumulate stale EC events, there does not seem to be any adverse side-effects of running the associated _Q methods. This patch adds an argument to the static function acpi_ec_sync_query so that it may be used within the acpi_ec_clear loop in place of acpi_ec_query_unlocked which was used previously. With thanks to Stefan Biereigel for reporting the issue, and for all the people who helped test the new patch on affected systems.

commit a8d22396 upstream. The ACPI PNP subsystem returns errors from pnpacpi_set_resources() and pnpacpi_disable_resources() if the _SRS or _DIS methods are not present, respectively, but it should not do that, because those methods are optional. For this reason, modify pnpacpi_set_resources() and pnpacpi_disable_resources(), respectively, to ignore missing _SRS or _DIS. This problem has been uncovered by commit 202317a5 (ACPI / scan: Add acpi_device objects for all device nodes in the namespace) and manifested itself by causing serial port suspend to fail on some systems.
