When I submitted the extcon handling I had a patch pending for the
extcon sub-system for extcon_register_notifier to take -1 as cable id
for listening for all type cable events on an extcon with a single
notifier.
In the end it was decided to instead add a new
extcon_register_notifier_all function for this, switch to using this.

On pm_runtime_get() failure, always emit an error message.
Prevent unbalanced pm_runtime_get by calling:
pm_runtime_put_noidle() in irq handler
pm_runtime_put_sync() on any probe() failure
Rename probe() out labels instead of renumbering them.

This adds a new driver for the LEGO MINDSTORMS EV3 battery. The EV3 is
an embedded ARM device that can use 6 AA batteries or a special rechargeable
Li-ion battery pack. The rechargeable battery pack presses a special key
switch in the battery compartment to indicate that it is present.
The EV3 is only capable of monitoring battery voltage and current. The
charging circuit is built into the rechargeable battery pack and there is
no way to communicate with is, so we can't provide any information about
charging status.
When not using the rechargeable battery pack, it is most common to use
alkaline batteries to power the device, but it is also common for people to
use rechargeable NiMH batteries. Since there is not a way to automatically
differentiate between these, the technology property is made writable.

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

The DT binding document for LTC2941 and LTC2943 battery gauges did not use

Add support for monitoring an extcon device with USB SDP/CDP/DCP and HOST
cables and adjust ilimit and enable/disable the 5V boost converter
accordingly. This is necessary on systems where the PSEL pin is hardwired
high and ILIM needs to be set by software based on the detected charger
type, as well as on systems where the 5V boost converter is used, as
that always needs to be enabled from software.

The bq24192 and bq24192i are mostly identical to the bq24190, TI even
published a single datasheet for all 3 of them. The difference
between the bq24190 and bq24192[i] is the way charger-type detection
is done, the bq24190 is to be directly connected to the USB a/b lines,
where as the the bq24192[i] has a gpio which should be driven high/low
externally depending on the type of charger connected, from a register
level access pov there is no difference.
The differences between the bq24192 and bq24192i are:
1) Lower default charge rate on the bq24192i
2) Pre-charge-current can be max 640 mA on the bq24192i
On x86/ACPI systems the code which instantiates the i2c client may not
know the exact variant being used, so instead of coding the model-id
in the i2c_id struct and bailing if it does not match, check the reported
model-id matches one of the supported variants.
This commit only adds support for the bq24192i as I don't
have a bq24192 to test with, adding support for the bq24192 should
be as simple as also accepting its model-id in the model-id test.

The Gemini (SL3516) SoC has a special power controller block
that only deal with shutting down the system.
If you do not register a driver and activate the block, the
power button on the systems utilizing this SoC will do an
uncontrolled power cut, which is why it is important to have
a special poweroff driver.
The most basic functionality is to just shut down the system
by writing a special bit in the control register after the
system has reached pm_poweroff.
It also handles the poweroff from a button or other sources:
When the poweroff button is pressed, or a signal is sent to
poweroff from an infrared remote control, or when the RTC
fires a special alarm (!) the system emits an interrupt.
At this point, Linux must acknowledge the interrupt and
proceed to do an orderly shutdown of the system.
After adding this driver, pressing the poweroff button gives
this dmesg:
root@gemini:/
root@gemini:/ gemini-poweroff 4b000000.power-controller:

Some SoCs like omap3 can configure GPIO irqs to use Linux generic
dedicated wakeirq support. If the dedicated wakeirq is configured,
the SoC will use a always-on interrupt controller to produce wake-up
events.
If bq24190 is configured for dedicated wakeirq, we need to check the
interrupt status on PM runtime resume. This is because the Linux
generic wakeirq will call pm_runtime_resume() on the device on a
wakeirq. And as the bq24190 interrupt is falling edge sensitive
and only active for 250 us, there will be no device interrupt seen
by the runtime SoC IRQ controller.
Note that this can cause spurious interrupts on omap3 devices with
bq24190 connected to gpio banks 2 - 5 as there's a glitch on those
pins waking from off mode as listed in "Advisory 1.45". Devices
with this issue should not configure the optional wakeirq interrupt
in the dts file.

Johannes Berg says:
====================
netlink extended ACK reporting
Changes since v4:
* use __NLMSGERR_ATTR_MAX instead of NUM_NLMSGERR_ATTRS
Changes since v3:
* Add NLM_F_CAPPED and NLM_F_ACK_TLVS flags, to allow entirely
stateless parsing of the ACK messages by looking at the new
flags. Need to check NLM_F_ACK_TLVS first, since capping can
be done in kernels before this patchset without setting the
flag.
* Remove "missing_attr" functionality - this can obviously be
added back rather easily, but I'd rather have more discussion
about the nesting problem there.
* Improve documentation of NLMSGERR_ATTR_OFFS
* Improve message structure documentation, documenting that the
request message is always capped for success cases
* fix nlmsg_len of the outer message by calling nlmsg_end()
* fix memcpy() of the request in success cases, going back to
the original code that I'd changed before due to the payload
adjustments that I reverted when introducing tlvlen
Changes since v2:
* add NUM_NLMSGERR_ATTRS, NLMSGERR_ATTR_MAX
* fix cookie length to 20 (sha-1 length)
* move struct members for cookie to patch 3 where they should be
* another cleanup suggested by David Ahern
Changes since v1:
* credit Pablo and Jamal
* incorporate suggestion from David Ahern
* fix compilation in decnet

Turns out that the LL protocol and the TI-ST are the same thing AFAICT.
The TI-ST adds firmware loading, GPIO control, and shared access for
NFC, FM radio, etc. For now, we're only implementing what is needed for
BT. This mirrors other drivers like BCM and Intel, but uses the new
serdev bus.
The firmware loading is greatly simplified by using existing
infrastructure to send commands. It may be a bit slower than the
original code using synchronous functions, but the real bottleneck is
likely doing firmware load at 115.2kbps.

1. Don't get the metric RTAX_ADVMSS of dst.
There are two reasons.
1) Its caller dst_metric_advmss has already invoke dst_metric_advmss
before invoke default_advmss.
2) The ipv4_default_advmss is used to get the default mss, it should
not try to get the metric like ip6_default_advmss.
2. Use sizeof(tcphdr)+sizeof(iphdr) instead of literal 40.
3. Define one new macro IPV4_MAX_PMTU instead of 65535 according to
RFC 2675, section 5.1.

David Ahern says:
====================
rtnetlink: Cleanup user notifications for netdev events
Vlad's recent patch to add the event type to rtnetlink notifications
points out a number of redundant or unnecessary notifications sent to
userspace for events that are essentially internal to the kernel. Trim
the list to put a dent in the notification storm.
v2
- rebased to top of net-next with IFLA_EVENT patch reverted
- dropped removal NETDEV_CHANGEINFODATA since it is intentionally
only to send a message to userspace
- dropped NOTIFY_PEERS since Vlad's says it is needed for macvlans
- add patches to remove NETDEV_CHANGEUPPER and NETDEV_CHANGE_TX_QUEUE_LEN
from the event list
====================

Changing tx queue length generates identical messages:

Remove NETDEV_CHANGE_TX_QUEUE_LEN from the list of notifiers that generate
notifications.
