acpi_get_object_info() allocates the returned structure, which the
caller has to free when the call succeeds. Free it when appropriate.

callbacks
All LED-setting functions in fujitsu-laptop are currently assigned to
the brightness_set callback, which is incorrect because they can sleep
(due to their use of call_fext_func(), which in turn issues ACPI calls)
and the documentation (in include/linux/leds.h) clearly states they must
not. Assign them to brightness_set_blocking instead and change them to
match the expected function prototype.
This change makes it possible to use Fujitsu-specific LEDs with "heavy"
triggers, like disk-activity or phy0rx.

When we teardown the backing storage for the phys object, we copy from
the coherent contiguous block back to the shmemfs object, clflushing as
we go. Trying to clflush the invalid sg beforehand just oops and would
be redundant (due to it already being coherent, and clflushed
afterwards).

The i915_gem_active stuff doesn't like a NULL ->retire hook, but
the overlay code can set it to NULL. That obviously ends up oopsing.
Fix it by introducing a new helper to assign the retirement callback
that will switch out the NULL function pointer with
i915_gem_retire_noop.

Trying to determine the pixel rate of the pipe can't be done until we
know the clock, which means it can't be done until the encoder
.get_config() hooks have been called. So let's move the min_pixclk[]
stuff to the end of intel_modeset_readout_hw_state() when we actually
have gathered all the required infromation.

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.
This fixes the following kind of warnings:

The pinctrl_gpio_request is called with the "full" gpio number, already
containing the base, then meson_pmx_request_gpio is then called with the
final pin number.
Remove the base addition when calling meson_pmx_disable_other_groups.

Pull ARM SoC fixes from Arnd Bergmann:
"This is a rather large set of bugfixes, as we just returned from the
Christmas break. Most of these are relatively unimportant fixes for
regressions introduced during the merge window, and about half of the
changes are for mach-omap2.
A couple of patches are just cleanups and dead code removal that I
would not normally have considered for merging after -rc2, but I
decided to take them along with the fixes this time.
Notable fixes include:
- removing the skeleton.dtsi include broke a number of machines, and
we have to put empty /chosen nodes back to be able to pass kernel
command lines as before
- enabling Samsung platforms no longer hardwires CONFIG_HZ to 200, as
it had been for no good reason for a long time"

Pull "SCPI fix for v4.10" from Sudeep Holla:
A simple fix for reading only lower 32-bit sensor values on pre-1.0 SCPI
firmwares so that upper 32-bit (garbage) value is discarded properly.
* tag 'scpi-fixes-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux:

The pre-1.0 SCPI firmwares are using single __le32 as sensor value,
while the SCPI v1.0 protocol uses two __le32 as sensor values(64bit)
split into 32bit upper and 32bit lower value.
Using an "struct sensor_value" to read the sensor value on a pre-1.0
SCPI firmware gives garbage in the "hi_val" field.
This patch fixes the issue by reading only the lower 32-bit value for
all pre-1.0 SCPI versions.

When the xenbus driver does some special handling for a Xenstore
command any error condition related to the command should be returned
via an error response instead of letting the related write operation
fail. Otherwise the user land handler might take wrong decisions
assuming the connection to Xenstore is broken.
While at it try to return the same error values xenstored would
return for those cases.

When accessing Xenstore in a transaction the user is specifying a
transaction id which he normally obtained from Xenstore when starting
the transaction. Xenstore is validating a transaction id against all
known transaction ids of the connection the request came in. As all
requests of a domain not being the one where Xenstore lives share
one connection, validation of transaction ids of different users of
Xenstore in that domain should be done by the kernel of that domain
being the multiplexer between the Xenstore users in that domain and
Xenstore.
In order to prohibit one Xenstore user "hijacking" a transaction from
another user the xenbus driver has to verify a given transaction id
against all known transaction ids of the user before forwarding it to
Xenstore.

Inserting the TSB means adding an extra 8 bytes in front the of packet
that is going to be used as metadata information by the TDMA engine, but
stripped off, so it does not really help with the packet padding.
For some odd packet sizes that fall below the 60 bytes payload (e.g: ARP)
we can end-up padding them after the TSB insertion, thus making them 64
bytes, but with the TDMA stripping off the first 8 bytes, they could
still be smaller than 64 bytes which is required to ingress the switch.
Fix this by swapping the padding and TSB insertion, guaranteeing that
the packets have the right sizes.
