Currently smatch warns of possible Spectre-V1 issue in ahci_led_store():
drivers/ata/libahci.c:1150 ahci_led_store() warn: potential spectre issue 'pp->em_priv' (local cap)
Userspace controls @pmp from following callchain:
em_message->store()
->ata_scsi_em_message_store()
-->ap->ops->em_store()
--->ahci_led_store()
After the mask+shift @pmp is effectively an 8b value, which is used to
index into an array of length 8, so sanitize the array index.

Few kernel applications like SCST-iSER create CQ using ib_create_cq(),
where accessing CQ structures using rdma restrack tool leads to below NULL
pointer dereference. This patch saves caller kernel module name similar to
ib_alloc_cq().

encoder/connector
One needs to ensure that the crtcs are shutdown so that the
drm_crtc_state->connector_mask reflects that no connectors
are currently active. Further, it reduces the reference
count for each connector. This ensures that the connectors
and encoders can be cleanly removed either when _unbind
is called for the corresponding drivers or by
drm_mode_config_cleanup().
We need drm_atomic_helper_shutdown() to be called before
component_unbind_all() otherwise the connectors attached to the
component device will have the wrong reference count value and will not
be cleanly removed.

The helper module would be unloaded after nf_conntrack_helper_unregister,
so it may cause a possible panic caused by race.
nf_ct_iterate_destroy(unhelp, me) reset the helper of conntrack as NULL,
but maybe someone has gotten the helper pointer during this period. Then
it would panic, when it accesses the helper and the module was unloaded.
Take an example as following:
CPU0 CPU1
ctnetlink_dump_helpinfo
helper = rcu_dereference(help->helper);
unhelp
set helper as NULL
unload helper module
helper->to_nlattr(skb, ct);
As above, the cpu0 tries to access the helper and its module is unloaded,
then the panic happens.

It is a waste of memory to use a full "struct netns_sysctl_ipv6"
while only one pointer is really used, considering netns_sysctl_ipv6
keeps growing.
Also, since "struct netns_frags" has cache line alignment,
it is better to move the frags_hdr pointer outside, otherwise
we spend a full cache line for this pointer.
This saves 192 bytes of memory per netns.

On this system EC interrupt triggers constantly kicking devices out of
low power states and thus blocking power management. The system also has
a PCIe root port hosting Alpine Ridge Thunderbolt controller and it
never gets a chance to go to D3cold because of this.
Since the power button works the same regardless if EC interrupt is
enabled or not during s2idle, add a quirk for this machine that sets
ec_no_wakeup=true preventing spurious wakeups.

Commit fe8abf332b8f ("usb: dwc3: support clocks and resets for DWC3 core")
adds support for handling clocks and resets in the DWC3 core, so that for
platforms following the standard devicetree bindings this does not need
to be duplicated in all the different glue layers.
These changes intended for devicetree based platforms introduce an
uncoditional clk_bulk_get() in the core probe path. This leads to the
following error being logged on x86/ACPI systems:
[ 26.276783] dwc3 dwc3.3.auto: Failed to get clk 'ref': -2
This commits wraps the clk_bulk_get() in an if (dev->of_node) check so
that it only is done on devicetree instantiated devices, fixing this
error.

This reverts commit 2c17a4368aad2b88b68e4390c819e226cf320f70.
The offending commit triggers a run-time fault when accessing the panel
element of the sun4i_tcon structure when no such panel is attached.
It was apparently assumed in said commit that a panel is always used with
the TCON. Although it is often the case, this is not always true.
For instance a bridge might be used instead of a panel.
This issue was discovered using an A13-OLinuXino, that uses the TCON
in RGB mode for a simple DAC-based VGA bridge.

Silicon Labs defines alternative VID/PID pairs for some chips that when
used will automatically install drivers for Windows users without manual
intervention. Unfortunately, these IDs are not recognized by the Linux
module, so using these IDs improves user experience on one platform but
degrades it on Linux. This patch addresses this problem.

The function, external interrupt controller, is made as an optional to
mt7622 pinctrl. But if we don't want pio behaves as an external interrupt
controller, it would lead to hw->eint not be created properly and then
will cause 'kernel NULL pointer' issue when gpiochip try to call .to_irq
or .set_config. To fix it, check hw->eint before accessing the member.
