Do not modify imgu_pipe->nodes[inode].vdev_fmt.fmt.pix_mp, until the
format has been correctly validated.
Otherwise, even if we use a backup variable, there is a period of time
where imgu_pipe->nodes[inode].vdev_fmt.fmt.pix_mp might have an invalid
value that can be used by other functions.

syzbot reported memory leak in dvb-usb. The problem was
in invalid error handling in dvb_usb_adapter_init().
for (n = 0; n < d->props.num_adapters; n++) {
....
if ((ret = dvb_usb_adapter_stream_init(adap)) ||
(ret = dvb_usb_adapter_dvb_init(adap, adapter_nrs)) ||
(ret = dvb_usb_adapter_frontend_init(adap))) {
return ret;
}
...
d->num_adapters_initialized++;
...
}
In case of error in dvb_usb_adapter_dvb_init() or
dvb_usb_adapter_dvb_init() d->num_adapters_initialized won't be
incremented, but dvb_usb_adapter_exit() relies on it:
for (n = 0; n < d->num_adapters_initialized; n++)
So, allocated objects won't be freed.

When CPU frequency is at 250 MHz and set_rate() is called with 500 MHz (L1)
quickly followed by a call with 1 GHz (L0), the CPU does not necessarily
stay in L1 for at least 20ms as is required by Marvell errata.
This situation happens frequently with the ondemand cpufreq governor and
can be also reproduced with userspace governor. In most cases it causes CPU
to crash.
This change fixes the above issue and ensures that the CPU always stays in
L1 for at least 20ms when switching from any state to L0.

The original CPU voltage value for load L1 is too low for Armada 37xx SoC
when base CPU frequency is 1000 or 1200 MHz. It leads to instabilities
where CPU gets stuck soon after dynamic voltage scaling from load L1 to L0.
Update the CPU voltage value for load L1 accordingly when base frequency is
1000 or 1200 MHz. The minimal L1 value for base CPU frequency 1000 MHz is
updated from the original 1.05V to 1.108V and for 1200 MHz is updated to
1.155V. This minimal L1 value is used only in the case when it is lower
than value for L0.
This change fixes CPU instability issues on 1 GHz and 1.2 GHz variants of
Espressobin and 1 GHz Turris Mox.
Marvell previously for 1 GHz variant of Espressobin provided a patch [1]
suitable only for their Marvell Linux kernel 4.4 fork which workarounded
this issue. Patch forced CPU voltage value to 1.108V in all loads. But
such change does not fix CPU instability issues on 1.2 GHz variants of
Armada 3720 SoC.
During testing we come to the conclusion that using 1.108V as minimal
value for L1 load makes 1 GHz variants of Espressobin and Turris Mox boards
stable. And similarly 1.155V for 1.2 GHz variant of Espressobin.
These two values 1.108V and 1.155V are documented in Armada 3700 Hardware
Specifications as typical initial CPU voltage values.
Discussion about this issue is also at the Armbian forum [2].

With CPU frequency determining software [1] we have discovered that
after this driver does one CPU frequency change, the base frequency of
the CPU is set to the frequency of TBG-A-P clock, instead of the TBG
that is parent to the CPU.
This can be reproduced on EspressoBIN and Turris MOX:
cd /sys/devices/system/cpu/cpufreq/policy0
echo powersave >scaling_governor
echo performance >scaling_governor
Running the mhz tool before this driver is loaded reports 1000 MHz, and
after loading the driver and executing commands above the tool reports
800 MHz.
The change of TBG clock selector is supposed to happen in function
armada37xx_cpufreq_dvfs_setup. Before the function returns, it does
this:
parent = clk_get_parent(clk);
clk_set_parent(clk, parent);
The armada-37xx-periph clock driver has the .set_parent method
implemented correctly for this, so if the method was actually called,
this would work. But since the introduction of the common clock
framework in commit b2476490ef11 ("clk: introduce the common clock..."),
the clk_set_parent function checks whether the parent is actually
changing, and if the requested new parent is same as the old parent
(which is obviously the case for the code above), the .set_parent method
is not called at all.
This patch fixes this issue by filling the correct TBG clock selector
directly in the armada37xx_cpufreq_dvfs_setup during the filling of
other registers at the same address. But the determination of CPU TBG
index cannot be done via the common clock framework, therefore we need
to access the North Bridge Peripheral Clock registers directly in this
driver.

ctx_q_num is a module parameter set by the user to specify the
number of qp queues required to create a ctx.
When the number of qp queues allocated by PF or VF is less than
the ctx_q_num, an error will be reported when ctx is initialized
in kernel mode, which leads to the problem that the registered
algorithms cannot be used.
Therefore, when PF or VF is initialized, if the number of qp queues
is not enough to create a ctx, the kernel mode cannot be used,
and there is no need to register the kernel mode algorithms.

soc: aspeed: Adapt to new LPC device tree layout
pinctrl: aspeed-g5: Adapt to new LPC device tree layout
ipmi: kcs: aspeed: Adapt to new LPC DTS layout

Previous kernels allowed the BLKROSET to override the disk's read-only
status. With that situation fixed the pmem driver needs to rely on
notification events to reevaluate the disk read-only status after the
host region has been marked read-write.
Recall that when libnvdimm determines that the persistent memory has
lost persistence (for example lack of energy to flush from DRAM to FLASH
on an NVDIMM-N device) it marks the region read-only, but that state can
be overridden by the user via:
echo 0 > /sys/bus/nd/devices/regionX/read_only
...to date there is no notification that the region has restored
persistence, so the user override is the only recovery.
