2016-04-13USB: uas: Limit qdepth at the scsi-host levelHans de Goede
Commit 64d513ac31bd ("scsi: use host wide tags by default") causes the SCSI core to queue more commands then we can handle on devices with multiple LUNs, limit the queue depth at the scsi-host level instead of per slave to fix this.

2016-04-13usb: host: xhci-plat: Make enum xhci_plat_type start at a non zero valuePeter Griffin
Otherwise generic-xhci and xhci-platform which have no data get wrongly detected as XHCI_PLAT_TYPE_MARVELL_ARMADA by xhci_plat_type_is(). This fixes a regression in v4.5 for STiH407 family SoC's which use the synopsis dwc3 IP, whereby the disable_clk error path gets taken due to wrongly being detected as XHCI_PLAT_TYPE_MARVELL_ARMADA and the hcd never gets added. I suspect this will also fix other dwc3 DT platforms such as Exynos, although I've only tested on STih410 SoC.

2016-04-13xhci: fix 10 second timeout on removal of PCI hotpluggable xhci controllersMathias Nyman
PCI hotpluggable xhci controllers such as some Alpine Ridge solutions will remove the xhci controller from the PCI bus when the last USB device is disconnected. Add a flag to indicate that the host is being removed to avoid queueing configure_endpoint commands for the dropped endpoints. For PCI hotplugged controllers this will prevent 5 second command timeouts For static xhci controllers the configure_endpoint command is not needed in the removal case as everything will be returned, freed, and the controller is reset. For now the flag is only set for PCI connected host controllers.

2016-04-13usb: host: xhci: add a new quirk XHCI_NO_64BIT_SUPPORTYoshihiro Shimoda
On some xHCI controllers (e.g. R-Car SoCs), the AC64 bit (bit 0) of HCCPARAMS1 is set to 1. However, the xHCs don't support 64-bit address memory pointers actually. So, in this case, this driver should call dma_set_coherent_mask(dev, DMA_BIT_MASK(32)) in xhci_gen_setup(). Otherwise, the xHCI controller will be died after a usb device is connected if it runs on above 4GB physical memory environment. So, this patch adds a new quirk XHCI_NO_64BIT_SUPPORT to resolve such an issue.

2016-04-13dmaengine: dw: fix master selectionAndy Shevchenko
The commit 895005202987 ("dmaengine: dw: apply both HS interfaces and remove slave_id usage") cleaned up the code to avoid usage of depricated slave_id member of generic slave configuration. Meanwhile it broke the master selection by removing important call to dwc_set_masters() in ->device_alloc_chan_resources() which copied masters from custom slave configuration to the internal channel structure. Everything works until now since there is no customized connection of DesignWare DMA IP to the bus, i.e. one bus and one or more masters are in use. The configurations where 2 masters are connected to the different masters are not working anymore. We are expecting one user of such configuration and need to select masters properly. Besides that it is obviously a performance regression since only one master is in use in multi-master configuration. Select masters in accordance with what user asked for. Keep this patch in a form more suitable for back porting. We are safe to take necessary data in ->device_alloc_chan_resources() because we don't support generic slave configuration embedded into custom one, and thus the only way to provide such is to use the parameter to a filter function which is called exactly before channel resource allocation. While here, replase BUG_ON to less noisy dev_warn() and prevent channel allocation in case of error.

2016-04-13ALSA: hda - Fix inconsistent monitor_present state until repollTakashi Iwai
While the previous commit fixed the missing monitor_present flag update, it may be still in an inconsistent state while the driver repolls: the flag itself is updated, but the eld_valid flag and the contents don't follow until the repoll finishes (and may be repeated for a few times). The basic problem is that pin_eld->monitor_present is updated in the caller side. This should have been updated only in update_eld(). So, the proper fix is to avoid accessing pin_eld but only spec->temp_eld. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-04-13ALSA: hda - Fix regression of monitor_present flag in eld proc fileHyungwon Hwang
The commit [bd48128539ab: ALSA: hda - Fix forgotten HDMI monitor_present update] covered the missing update of monitor_present flag, but this caused a regression for devices without the i915 eld notifier. Since the old code supposed that pin_eld->monitor_present was updated by the caller side, the hdmi_present_sense_via_verbs() doesn't update the temporary eld->monitor_present but only pin_eld->monitor_present, which is now overridden in update_eld(). The fix is to update pin_eld->monitor_present as well before calling update_eld(). Note that this may still leave monitor_present flag in an inconsistent state when the driver repolls, but this is at least the old behavior. More proper fix will follow in the later patch.

2016-04-12debugfs: Make automount point inodes permanently emptySeth Forshee
Starting with 4.1 the tracing subsystem has its own filesystem which is automounted in the tracing subdirectory of debugfs. Prior to this debugfs could be bind mounted in a cloned mount namespace, but if tracefs has been mounted under debugfs this now fails because there is a locked child mount. This creates a regression for container software which bind mounts debugfs to satisfy the assumption of some userspace software. In other pseudo filesystems such as proc and sysfs we're already creating mountpoints like this in such a way that no dirents can be created in the directories, allowing them to be exceptions to some MNT_LOCKED tests. In fact we're already do this for the tracefs mountpoint in sysfs. Do the same in debugfs_create_automount(), since the intention here is clearly to create a mountpoint. This fixes the regression, as locked child mounts on permanently empty directories do not cause a bind mount to fail.

Commit 254d4d111ee1 ("drm/exynos: Add dependency for G2D in Kconfig") made the DRM_EXYNOS_G2D symbol to only be selectable if the s5p-g2d V4L2 driver is not enabled, since both use the same HW IP block. But added the dependency as depends on !VIDEO_SAMSUNG_S5P_G2D which isn't correct since Kconfig expressions are not boolean but tristate. So it will only evaluate to 'n' if VIDEO_SAMSUNG_S5P_G2D=y but it will evaluate to m if VIDEO_SAMSUNG_S5P_G2D=m. This means that both the V4L2 and DRM drivers can be enabled if the former is enabled as a module, which is not what we want.

2016-04-12mailbox: mailbox-test: Prevent memory leakLee Jones
If we set the Signal twice or more, without using it as part of a message, memory will be re-allocated and the pointer over-written. Prevent this potential leak by only allocating memory when there isn't any already.

2016-04-11NVMe: Fix reset/remove raceKeith Busch
This fixes a scenario where device is present and being reset, but a request to unbind the driver occurs. A previous patch series addressing a device failure removal scenario flushed reset_work after controller disable to unblock reset_work waiting on a completion that wouldn't occur. This isn't safe as-is. The broken scenario can potentially be induced with: modprobe nvme && modprobe -r nvme To fix, the reset work is flushed immediately after setting the controller removing flag, and any subsequent reset will not proceed with controller initialization if the flag is set. The controller status must be polled while active, so the watchdog timer is also left active until the controller is disabled to cleanup requests that may be stuck during namespace removal.

2016-04-11dm: fix dm_target_io leak if clone_bio() returns an errorMikulas Patocka
Commit c80914e81ec5b08 ("dm: return error if bio_integrity_clone() fails in clone_bio()") changed clone_bio() such that if it does return error then the alloc_tio() created resources (both the bio that was allocated to be a clone and the containing dm_target_io struct) will leak. Fix this by calling free_tio() in __clone_and_map_data_bio()'s clone_bio() error path.

The 'size' member of a struct firmware is passed to snd_printk with a respective format string using the %d identifier. The 'size' member is of type size_t, but format identifier %d indicates a signed int data type. This patch replaces the %d format identifier with the correct %zu format identifier for size_t data types.
