The resource_size defines that:
res->end - res->start + 1;
The origin original code is:
sysmgr_config.max_register = res->end - res->start - 3;
So, the correct fix is that:
sysmgr_config.max_register = resource_size(res) - 4;
Fixes: d12edf9661a4 ("mfd: altera-sysmgr: Use resource_size function on resource object")

The X-Powers AXP PMICs feature a GPIO Controller supported by Linux
thanks to its device tree binding.
Now that we have the DT validation in place, let's convert the device
tree bindings for that driver over to a YAML schema.

The Arizona driver has both some devices which only have an I2C
interface and some which only have a SPI interface. Currently both of
these share an of_match table, but this means inapproriate compatibles
are available for each interface. Tidy this up by creating a table for
each interface listing only the appropriate compatibles.

PM8xxx PMIC family uses GPIO as parent IRQ. Using it together with the
irq_set_chained_handler_and_data() results in warnings from the GPIOLIB
(see 461c1a7d4733 ("gpiolib: override irq_enable/disable"))
as in this path the IRQ resources are not allocated (and thus the
corresponding GPIO is not marked as used for the IRQ. Use request_irq so
that the IRQ resources are proprely setup.

Interrupt line can be configured on different hardware in different way,
even inverted. Therefore driver should not enforce specific trigger
type - edge falling - but instead rely on Devicetree to configure it.
The Maxim 14577/77836 datasheets describe the interrupt line as active
low with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.
The interrupt line is shared between PMIC and charger driver, so using
level sensitive interrupt is here especially important to avoid races.
With an edge configuration in case if first PMIC signals interrupt
followed shortly after by the RTC, the interrupt might not be yet
cleared/acked thus the second one would not be noticed.

even inverted. Therefore driver should not enforce specific trigger
type - edge falling - but instead rely on Devicetree to configure it.
The Maxim 77693 datasheet describes the interrupt line as active low
with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.
The interrupt line is shared between PMIC and RTC driver, so using level
sensitive interrupt is here especially important to avoid races. With
an edge configuration in case if first PMIC signals interrupt followed
shortly after by the RTC, the interrupt might not be yet cleared/acked
thus the second one would not be noticed.

even inverted. Therefore driver should not enforce specific trigger

The Samsung PMIC drivers are used only on Devicetree boards.
Additionally, the PMIC datasheets describe the interrupt line as active
low with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.

The Pericom PI7C9X2G404/PI7C9X2G304/PI7C9X2G303 PCIe switches have an
erratum for ACS P2P Request Redirect behaviour when used in the cut-through
forwarding mode. The recommended work around for this issue is to use the
switch in store and forward mode. The erratum results in packets being
queued and not being delivered upstream, which can be observed as very poor
downstream device performance and/or dropped device-generated
data/interrupts.
Add a fixup so that when enabling or resuming the downstream port we check
if it has enabled ACS P2P Request Redirect, and if so, change the device
(via the upstream port) to use the store and forward operating mode.

udp_mem is a vector of 3 INTEGERs, which is used to limit the number of
pages allowed for queueing by all UDP sockets.
However, sk_has_memory_pressure() in __sk_mem_raise_allocated() always
return false for udp, as memory pressure is not supported by udp, which
means that __sk_mem_raise_allocated() will fail once pages allocated
for udp socket exceeds udp_mem[0].
Therefor, udp_mem[0] is the only one that limit the number of pages.
However, the document of udp_mem just express that udp_mem[2] is the
limitation. So, just fix it.
