We need to actually make sure we check this on resume since otherwise we
won't know whether or not the topology is still there once we've
resumed, which will cause us to still think the topology is connected
even after it's been removed if the removal happens mid-suspend.

As part of commit cfea88a4d866 ("drm/nouveau: Start using new drm_dev
initialization helpers"), the initialization of the Nouveau DRM device
was reworked and along the way the platform driver initialization was
left incomplete. Add a call to nouveau_drm_device_init() to make sure
all of the structures are properly initialized.

Adding brackets allows to multiply the register value,
masked by TS1_RAMP_COEFF_MASK, by an ADJUST value
properly and not to multiply ADJUST by register value and
then mask the whole.

Calling stm_thermal_read_factory_settings before clocking
internal peripheral causes bad register values and makes
temperature computation wrong.
Calling stm_thermal_read_factory_settings inside
stm_thermal_prepare fixes this problem as internal
peripheral is well clocked at this stage.

Without this patch the thermal driver is broken on hi3660.
The dual sensors support patchset was partially merged, unfortunately
the dual thermal zones definition is not available in the DT yet, so
when the driver tries to register all the sensors that fails.
By reducing to 1 the number of sensors on the hi3660, we switch back
to the previous functionnality.

Without this patch, the thermal driver on hi6220 and hi3660 is broken.
That is due because part of the posted patchset was merged but a small
change in the DT was dropped.
The hi6220 and hi3660 do not have an interrupt name in the DT, so
finding interrupt by name fails.
Fix this by returning back to the platform_get_irq() function call.

Exchange LED configuration between msn201x and next generation systems
types.
Bug was introduced when LED driver activation was added to mlx-platform.
LED configuration for the three new system MQMB7, MSN37, MSN34 was
assigned to MSN21 and vice versa. This bug affects MSN21 only and
likely requires backport to v4.19.

Shift by one the registers for tachometers (7 - 12).
This fix is relevant for the same new systems MQMB7, MSN37, MSN34,
which are about to be released to the customers.
At the moment, none of them is at customers sites. The customers will
not suffer from this change.
This fix is necessary, because register used before for tachometer 7
has been than reserved for the second PWM for newer systems, which are
not supported yet in mlx-platform driver. So registers of tachometers
7-12 have been shifted by one.

net/ibmvnic: Fix reset work item locking bugs
This patch set fixes issues with scheduling reset work items in

vr.vifi is indirectly controlled by user-space, hence leading to
a potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
net/ipv4/ipmr.c:1616 ipmr_ioctl() warn: potential spectre issue 'mrt->vif_table' [r] (local cap)
net/ipv4/ipmr.c:1690 ipmr_compat_ioctl() warn: potential spectre issue 'mrt->vif_table' [r] (local cap)
Fix this by sanitizing vr.vifi before using it to index mrt->vif_table'
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

sin6_flowinfo is not really used by SCTP, so it will be fixed by simply
setting it to 0.
The issue exists since very beginning.
Thanks Alexander for the reproducer provided.

I get a segfault without it, other fixups always do dereference, and
without dereference I don't understand how it can ever work.

- A bugfix for MMP2 CPU detection, it's been there quite a while but
makes sense to fix now anyway.
- Some power management tweaks:
+ disabling of CPU idle power state on Marvell Armada 7K/8K
(Macchiatobin et al)
+ Increase of minimum voltage on BananaPi M3
+ Tweak of power ramp time for DVFS on NXP/Freescale i.MX7SX

+ MMP has a new volunteer to look after it

Commit '88ba95bedb79 ("backlight: pwm_bl: Compute brightness of LED
linearly to human eye")' allows the possibility to compute a default
brightness table when there isn't the brightness-levels property in the
DT. Unfortunately the changes made broke the pwm backlight for the
non-DT boards.
Usually, the non-DT boards don't pass the brightness levels via platform
data, instead, it sets the max_brightness in their platform data and the
driver calculates the level without a table. The offending patch assumed
that when there is no brightness levels table we should create one, but this
is clearly wrong for the non-DT case.
After this patch the code handles the DT and the non-DT case taking in
consideration also if max_brightness is set or not.

The known ALC256_FIXUP_ASUS_MIC fixup can fix the headphone jack
sensing and enable use of the internal microphone on this laptop
X542UN. However, it's ALC294 so create a new fixup named
ALC294_FIXUP_ASUS_MIC to avoid confusion.
