drm/i915: Split skl_update_scaler, v4.
It's easier to read separate functions for crtc and plane scaler state.
Changes since v1:
- Update documentation.
Changes since v2:
- Get rid of parameters to skl_update_scaler only used for traces.
This avoids needing to document the other parameters.
Changes since v3:
- Rename scaler_idx to scaler_user.

The scaler setup may add planes, but since they're unchanged we only
have to wait for primary flips. Also set planes_changed to indicate
at least 1 plane is modified.

If jffs2 can deadlock on overlayfs readdir because it takes the same lock
on ->iterate() as in ->lookup().
Fix by moving whiteout checking outside iterate_dir(). Optimized by
collecting potential whiteouts (DT_CHR) in a temporary list and if
non-empty iterating throug these and checking for a 0/0 chardev.

Allow filesystems with .d_revalidate as lower layer(s), but not as upper
layer.
For local filesystems the rule was that modifications on the layers
directly while being part of the overlay results in undefined behavior.
This can easily be extended to distributed filesystems: we assume the tree
used as lower layer is static, which means ->d_revalidate() should always
return "1". If that is not the case, return -ESTALE, don't try to work
around the modification.

NFS and other distributed filesystems may place automount points in the
tree. Previoulsy overlayfs refused to mount such filesystems types (based
on the existence of the .d_automount callback), even if the actual export
didn't have any automount points.
It cannot be determined in advance whether the filesystem has automount
points or not. The solution is to allow fs with .d_automount but refuse to
traverse any automount points encountered.

The enable field needs to be kept in sync with the mode_blob field. Call

ASoC: A couple more updates for v4.2

Using -1 as platform device id means that the platform driver core will not
assign any id to the device (the device name will not have id at all). This
results problems on systems that have multiple PCHs (Platform Controller
HUBs) because all of them also include their own copy of LPC device.
All the subsequent device creations will fail because there already exists
platform device with the same name.
Fix this by passing PLATFORM_DEVID_AUTO as platform device id. This makes
the platform device core to allocate new ids automatically.

Add MFD support for the DA9063 OnKey driver
The function da9063_clear_fault_log() is added to mitigate the case of a
hardware power-cut after a long-long OnKey press. Although there is no
software intervention in this case (by definition) such a shutdown would
cause persistent information within the DA9063 FAULT_LOG that would be
available during the next device restart.
Clearance of this persistent register must be completed after such a
hardware power-cut operation has happened so that the FAULT_LOG does not
continue with previous values. The clearance function has been added here
in the kernel driver because wiping the fault-log cannot be counted on
outside the Linux kernel.

Current code in mfd-core calls into ACPI to check resources even
on a system that booted with a DT (on kernels with both DT and ACPI
support compiled in). This triggers ACPI exceptions since we may
end up calling the ACPI interpreter when it has not been initialized:
"ACPI Exception: AE_BAD_PARAMETER, Thread 2064154624 could not acquire
Mutex [0x1] (20150410/utmutex-285)"
This patch fixes the issues by adding a check for an ACPI companion
device before carrying out ACPI resources checks to avoid calling
the ACPI interpreter if the fwnode representing the device is an OF one.

Allow the chip to completely power off if we enter runtime suspend and
there is no jack detection active. This is helpful for systems where
system suspend might remove the supplies to the CODEC, without informing
us. Note the powering off is done in runtime suspend rather than system
suspend, because we need to hold reset until the first time DCVDD is
powered anyway (which would be in runtime resume), and we might as well
save the extra power.

The wm5102 uses a custom boot sequence and the standard boot sequence is
disabled. However, the standard boot sequence must be run at least once
after a cold boot (caused by either a hard reset or removal of AVDD).
Unfortunately the register WRITE_SEQUENCER_CTRL_3 is not affected by the
hardware reset. This means if the device has been previously booted but
the AVDD supply has never been removed, arizona_dev_init will reset the
chip but the boot sequence will not run, which can cause numerous
problems. The solution is to manually clear this register and then boot
the chip again, which is what this patch does.
