It's not always true that the device_node of regulator can be found
at dev->of_node at the time when of_get_regulator_init_data() is being
called, because in some cases the regulator nodes in device tree do
not have 'struct device' behind them until regulator_dev gets created
for it by core function regulator_register().The patch adds device_node as a new parameter to
of_get_regulator_init_data(), so that caller can pass in the node of
regulator directly.Signed-off-by: Shawn Guo

Otherwise there is no way in the bindings to configure a fixed voltage
via software. It seems reasonable to assume that if the binding explicitly
specifies a voltage we want to actually use that voltage.Signed-off-by: Mark Brown

The commit 2c043bcbf287 ("regulator: pass additional of_node to
regulator_register()") added an additional parameter to the
regulator_register() API.
Update the Documentation accordingly to reflect the change
in the function signature.Reported-by: Thomas Abraham

The commit 2c043bcbf287 ("regulator: pass additional of_node to
regulator_register()") caused a compile break because it missed
updating the regulator_register() call in gpio-regulator.c with
the additional parameter (NULL).The compile break as reported by Stephen Rothwell with the
x86_64 allmodconfig looked like thisdrivers/regulator/gpio-regulator.c: In function 'gpio_regulator_probe':

Device nodes in DT can associate themselves with one or more
regulators/supply by providing a list of phandles (to regulator nodes)
and corresponding supply names.For Example:
devicenode: node@0x0 {
...
...
vmmc-supply = ;
vpll-supply = ;
};The driver would then do a regulator_get(dev, "vmmc"); to get
regulator1 and do a regulator_get(dev, "vpll"); to get
regulator2.of_get_regulator() extracts the regulator node for a given
device, based on the supply name.Use it to look up the regulator for a given consumer from device tree, during
a regulator_get(). If not found fallback and lookup through
the regulator_map_list instead.Also, since the regulator dt nodes can use the same binding to
associate with a parent regulator/supply, allow the drivers to
specify a supply_name, which can then be used to lookup dt
to find the parent phandle.Signed-off-by: Rajendra Nayak

With device tree support for regulators, its needed that the
regulator_dev->dev device has the right of_node attached.
To be able to do this add an additional parameter to the
regulator_register() api, wherein the dt-adapted driver can
then pass this additional info onto the regulator core.Signed-off-by: Rajendra Nayak

The fixed regulator driver uses of_get_fixed_voltage_config()
to extract fixed_voltage_config structure contents from device tree.Also add documenation for additional bindings for fixed
regulators that can be passed through dt.Signed-off-by: Rajendra Nayak
Signed-off-by: Mark Brown -
The helper routine is meant to be used by the regulator drivers
to extract the regulator_init_data structure from the data
that is passed from device tree.
'consumer_supplies' which is part of regulator_init_data is not extracted
as the regulator consumer mappings are passed through DT differently,
implemented in subsequent patches.
Similarly the regulatorparent/supply mapping is handled in
subsequent patches.Also add documentation for regulator bindings to be used to pass
regulator_init_data struct information from device tree.Some of the regulator properties which are linux and board specific,
are left out since its not clear if they can
be in someway embedded into the kernel or passed in from DT.
They will be revisited later.Signed-off-by: Rajendra Nayak

Commit 8dc7a9c84 ("blackfin: Add export.h to files using

virtio-pci: fix use after free -
Commit 31a3ddda166cda86d2b5111e09ba4bda5239fae6 introduced
a use after free in virtio-pci. The main issue is
that the release method signals removal of the virtio device,
while remove signals removal of the pci device.For example, on driver removal or hot-unplug,
virtio_pci_release_dev is called before virtio_pci_remove.
We then might get a crash as virtio_pci_remove tries to use the
device freed by virtio_pci_release_dev.We allocate/free all resources together with the
pci device, so we can leave the release method empty.Signed-off-by: Michael S. Tsirkin

After commit e978aa7d7d57 ("cpuidle: Move dev->last_residency update to
driver enter routine; remove dev->last_state") setting acpi_idle_suspend
to 1 by acpi_processor_suspend() causes the ACPI cpuidle routines to
return error codes continuously, which in turn causes cpuidle to lock up
(hard).However, acpi_idle_suspend doesn't appear to be useful for any
particular purpose (it's racy and doesn't really provide any real
protection), so it can be removed, which makes the problem go away.Reported-and-tested-by: Tomas M.

Real world year equals the value in vrtc YEAR register plus an offset.
We used 1960 as the offset to make leap year consistent, but for a
device's first use, its YEAR register is 0 and the system year will
be parsed as 1960 which is not a valid UNIX time and will cause many
applications to fail mysteriously. So we use 1972 instead to fix this
issue.Updated patch which adds a sanity check suggested by Mathias
