Commit 8067302973a1 ("net-next: mediatek: add support for IRQ grouping")
adds handling for irq 1 and 2 to the uninit function but did not remove
irq 0 which is not used since irq grouping was introduced. Fix this by
removing the superfluous call to free_irq().

This feature patchset includes the following changes:
- Cleanup work by Markus Pargmann and Sven Eckelmann (six patches)
- Initial Netlink support by Matthias Schiffer (two patches)
- Throughput Meter implementation by Antonio Quartulli, a kernel-space
traffic generator to estimate link speeds. This feature is useful on
low-end WiFi APs where running iperf or netperf from userspace
gives wrong results due to heavy userspace/kernelspace overhead.
(two patches)

As with the previously introduced L3 interfaces, listen to 'inetaddr'
notifications sent for bridges devices configured on top of the port
netdevs and create / destroy router interfaces (RIFs) accordingly.
This also includes VLAN devices configured on top of the VLAN-aware
bridge.
The RIFs will be destroyed either when the last IP address is removed or
when the underlying FID is is destroyed.

Before introducing support for L3 interfaces on top of the VLAN-aware
bridge we need to add some missing infrastructure.
Such an interface can either be the bridge device itself or a VLAN
device on top of it. In the first case the router interface (RIF) is
associated with FID 1, which is created whenever the first port netdev
joins the bridge. We currently assume the default PVID is 1 and that
it's already created, as it seems reasonable. This can be extended in
the future.
However, in the second case it's entirely possible we've yet to create a
matching FID. This can happen if the VLAN device was configured before
making any bridge port member in the VLAN.
Prevent such ordering problems by using the VLAN device's CHANGEUPPER
event to configure the FID. Make the VLAN device hold a reference to the
FID and prevent it from being destroyed even if none of the port netdevs
is using it.

Up until now we only supported bridged interfaces. Packets ingressing
through the switch ports were either classified to FIDs (in the case of
the VLAN-aware bridge) or vFIDs (in the case of VLAN-unaware bridges).
The packets were then forwarded according to the FDB. Routing was done
entirely in slowpath, by splitting the vFID range in two and using the
lower 0.5K vFIDs as dummy bridges that simply flooded all incoming
traffic to the CPU.
Instead, allow packets to be routed in the device by creating router
interfaces (RIFs) that will direct them to the router block.
Specifically, the RIFs introduced here are Sub-port RIFs used for VLAN
devices and port netdevs. Packets ingressing from the {Port / LAG ID, VID}
with which the RIF was programmed with will be assigned to a special
kind of FIDs called rFIDs and from there directed to the router.
Create a RIF whenever the first IPv4 address was programmed on a VLAN /
LAG / port netdev. Destroy it upon removal of the last IPv4 address.
Receive these notifications by registering for the 'inetaddr'
notification chain. A non-zero (10) priority is used for the
notification block, so that RIFs will be created before routes are
offloaded via FIB code.
Note that another trigger for RIF destruction are CHANGEUPPER
notifications causing the underlying FID's reference count to go down to
zero. This can happen, for example, when a VLAN netdev with an IP address
is put under bridge. While this configuration doesn't make sense it does
cause the device and the kernel to get out of sync when the netdev is
unbridged. We intend to address this in the future, hopefully in current
cycle.
Finally, Remove the lower 0.5K vFIDs, as they are deprecated by the RIFs,
which will trap packets according to their DIP.

We are just about to introduce router interfaces (RIFs), but before that
we need to be able update the device with the correct RIF attributes
whenever they change for the netdev the RIF is backing. Two such
attributes are MTU and MAC.
The MAC is used both to set the source MAC of packets egressing from the
RIF and also to program an FDB rule that will direct packets to the
router block.
Use the existing netdevice notification block and respond to CHANGEADDR
and CHANGEMTU accordingly. Store both attributes in the RIF struct
in case we need to revert to old attributes following a failed update.

Noticed by the build system, that emitted this warning:
Warning: x86_64's syscall_64.tbl differs from kernel
This was due to the wiring up of the recently added preadv2 & pwritev2
syscalls to the compat code, which hadn't been done by the patch
introducing those syscalls: 4babf2c5efb7 ("x86: wire up preadv2 and
pwritev2").
The patch doing the compat wiring was:
482dd2ef1244 ("x86/syscalls: Wire up compat readv2/writev2 syscalls")
This just silences the perf build warning, as compat syscalls still
can't be supported in 'perf trace´ due to limitations in the
raw_syscalls:sys_{enter,exit} tracepoints it relies on.

In 2011, commit 774466add7c ("hwmon: (jc42) Change detection class")
changed the detection class of these chips to I2C_CLASS_SPD based
on this premise: "makes more sense because these chips always live on
memory modules"
Today these chips have applications beyond memory modules. Examples are
JC42.4 compatible chips such as MCP9804 and MCP9808, but also MCP9805,
which is marked as JC42.4 compliant and suggested for use not only for
DIMMS, but also as generic temperature sensor.
Add I2C_CLASS_HWMON as an additional detection class to allow detection
by hwmon class i2c adapters.

Several Lenovo users have reported problems with their Sierra
Wireless EM7455 modem. The driver has loaded successfully and
the MBIM management channel has appeared to work, including
establishing a connection to the mobile network. But no frames
have been received over the data interface.
The problem affects all EM7455 and MC7455, and is assumed to
affect other modems based on the same Qualcomm chipset and
baseband firmware.
Testing narrowed the problem down to what seems to be a
firmware timing bug during initialization. Adding a short sleep
while probing is sufficient to make the problem disappear.
Experiments have shown that 1-2 ms is too little to have any
effect, while 10-20 ms is enough to reliably succeed.
