2017-01-03Btrfs: fix lockdep warning about log_mutexLiu Bo
While checking INODE_REF/INODE_EXTREF for a corner case, we may acquire a different inode's log_mutex with holding the current inode's log_mutex, and lockdep has complained this with a possilble deadlock warning. Fix this by using mutex_lock_nested() when processing the other inode's log_mutex.

In __btrfs_run_delayed_refs, when we put back a delayed ref that's too new, we have already dropped the lock on locked_ref when we set ->processing = 0.

The most important of which is a big regression on dwc3-pci which prevents it from probing altogether. There's also a fix to avoid Overflow events on DWC3 and another to make sure we don't starve DMA resources. Dummy HCD got some love after a long hiatus and DWC2 got a couple fixes related to DMA usage. Other than these, we have a set of minor fixes here and there.

2017-01-03drm/i915: Force VDD off on the new power seqeuencer before starting to use itVille Syrjälä
Apparently some VLV BIOSen like to leave the VDD force bit enabled even for power seqeuncers that aren't properly hooked up to any port. That will result in a imbalance in the AUX power domain refcount when we stat to use said power sequencer as edp_panel_vdd_on() will not grab the power domain reference if it sees that the VDD is already on. To fix this let's make sure we turn off the VDD force bit when we initialize the power sequencer registers. That is, unless it's being done from the init path since there we are actually initializing the registers for the current power sequencer and we don't want to turn VDD off needlessly as that would require waiting for the power cycle delay before we turn it back on.

Having the pin control framework call pin controller functions before it's probe has finished is not nice as the pin controller device driver does not yet have struct pinctrl_dev handle. Let's fix this issue by adding deferred work for late init. This is needed to be able to add pinctrl generic helper functions that expect to know struct pinctrl_dev handle. Note that we now need to call create_pinctrl() directly as we don't want to add the pin controller to the list of controllers until the hogs are claimed. We also need to pass the pinctrl_dev to the device tree parser functions as they otherwise won't find the right controller at this point.

2017-01-03PM / devfreq: Fix the bug of devfreq_add_device when governor is NULLChanwoo Choi
This patch fixes the bug of devfreq_add_device(). The devfreq device must have the default governor. If find_devfreq_governor() returns error, devfreq_add_device() fail to add the devfreq instance.

2017-01-03MAINTAINERS: Add myself as reviewer for DEVFREQ subsystem supportChanwoo Choi
Add myself to the DEVFREQ entry as reviewer, I've been helping reviewing and tesing the devfreq support patches for the couple of years. Also, I'm going to contribute the improvement for devfreq subsystem. It would be easier for me for review if I'm cc'ed for patches.

2017-01-03PM / docs: Drop confusing kernel-doc references from infrastructure.rstRafael J. Wysocki
The references to drivers/base/power/main.c and drivers/acpi/scan.c from Documentation/driver-api/infrastructure.rst are confusing. They both cause descriptions of functions that are not relevant to device drivers at all to be generated and none of them is sufficient to cover the API in a meaningful way. Drop them for now.

2017-01-02ACPI / scan: Prefer devices without _HID/_CID for _ADR matchingRafael J. Wysocki
The way acpi_find_child_device() works currently is that, if there are two (or more) devices with the same _ADR value in the same namespace scope (which is not specifically allowed by the spec and the OS behavior in that case is not defined), the first one of them found to be present (with the help of _STA) will be returned. This covers the majority of cases, but is not sufficient if some of the devices in question have a _HID (or _CID) returning some valid ACPI/PNP device IDs (which is disallowed by the spec) and the ASL writers' expectation appears to be that the OS will match devices without a valid ACPI/PNP device ID against a given bus address first. To cover this special case as well, modify find_child_checks() to prefer devices without ACPI/PNP device IDs over devices that have them.
