The alternative stack checking in get_sigframe introduced by the Vector
support is not needed and has a problem. It is not needed as we have
already validate it at the beginning of the function if we are already
on an altstack. If not, the size of an altstack is always validated at
its allocation stage with sigaltstack_size_valid().
Besides, we must only regard the size of an altstack if the handler of a
signal is registered with SA_ONSTACK. So, blindly checking overflow of
an altstack if sas_ss_size not equals to zero will check against wrong
signal handlers if only a subset of signals are registered with
SA_ONSTACK.

Current mechanism replaces "%d" present in some routes and widget names
with SSP number. However there are also configurations which make use of
TDM number, in which case expected behavior would be to have string in
form of SSP:TDM - see implementation of avs_i2s_platform_register() in
sound/soc/intel/avs/pcm.c.
Implement custom function, which parses string and make use of it when
parsing topology. While at it make sure that we generate dynamic names
only if there is no multiple SSPs or TDMs defined.

In quite a few places in code there are checks for number of SSPs
present on system, to reduce maintenance burden introduce helper
functions allowing to get SSP and TDM from machine board configuration.
Additionally in boards we use SSP and TDM to generate quite a few
strings, it could be done like:
if (tdms)
dl->name = devm_kasprintf(dev, GFP_KERNEL, "SSP%d:%d-Codec",
ssp_port, tdm_slot);
else
dl->name = devm_kasprintf(dev, GFP_KERNEL, "SSP%d-Codec",
ssp_port);
but quite quickly code ends up with spaghetti of similar if elses.
Instead introduce macro which can be used to generate correct string,
allowing to minimize code to something like:
dl->name = devm_kasprintf(dev, GFP_KERNEL, AVS_STRING_FMT("SSP", "-Codec",
ssp_port, tdm_slot));

Merge tag 'dt64-cleanup-6.7' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-dt into soc/dt
Minor improvements in ARM64 DTS for v6.7
Few cleanups and improvements: use lowercase hex for unit addresses
(Bitmain), add missing spaces before '{' (APM, MediaTek) and cleanup
whitespace around '=' (MediaTek, Marvell).

On the Lenovo Yoga Tab 3 Pro YT3-X90F there are 2 issues with the backlight
on/off MIPI sequences:
1. The backlight on sequence has an I2C MIPI sequence element which uses
bus 0, but there is a bogus I2cSerialBus resource under the GPU in
the DSDT which causes i2c_acpi_find_adapter() to pick the wrong bus.
2. There is no backlight off sequence, causing the backlight to stay on.
Add a DMI quirk fixing both issues.
v2:
- Add Closes tag to gitlab issue with drm.debug=0xe, VBT info

On the Lenovo Yoga Tablet 2 830 / 1050 there are 2 problems:
1. The I2C MIPI sequence elements reference bus 3. ACPI has I2C1 - I2C7
which under Linux become bus 0 - 6. And the MIPI sequence reference
to bus 3 is indented for I2C3 which is bus 2 under Linux.
This leads to errors like these:
[ 178.244049] i2c_designware 80860F41:03: controller timed out
[ 178.245703] i915 0000:00:02.0: [drm] *ERROR* Failed to xfer payload of size (1) to reg (169)
There are 3 timeouts when the panel is on, delaying
waking up the screen on a key press by 3 seconds.
Note mipi_exec_i2c() cannot just subtract 1 from the bus
given in the I2C MIPI sequence element. Since on other
devices the I2C bus-numbers used in the MIPI sequences do
actually start at 0.
2. width_/height_mm contain a bogus 192mm x 120mm size. This is
especially a problem on the 8" 830 version which uses a 10:16
portrait screen where as the bogus size is 16:10.
Add a DMI quirk to override the I2C bus and the panel size with
the correct values.
Note both the 10" 1050 models as well as the 8" 830 models use the same
mainboard and thus the same DMI strings. The 10" 1050 uses a 1920x1200
landscape screen, where as the 8" 830 uses a 1200x1920 portrait screen,
so the quirk handling uses the display resolution to detect the model.
v2:
- Also override i2c_bus_num to fix mipi_exec_i2c() timeouts
v3:
- Add Closes tag to gitlab issue with drm.debug=0xe, VBT info

Vtotal is wrong in the BIOS supplied modeline for the DSI panel on
the Asus TF103C leading to the last line of the display being shown
as the first line.
Original: "1280x800": 60 67700 1280 1312 1328 1376 800 808 812 820 0x8 0xa
Fixed: "1280x800": 60 67700 1280 1312 1328 1376 800 808 812 816 0x8 0xa
The factory installed Android has a hardcoded modeline in its kernel,
causing it to not suffer from this BIOS bug;
and the Android boot-splash which uses the EFI FB which does have this bug
has the last line all black causing the bug to not be visible.
This commit introduces a generic DMI based quirk mechanism to vlv_dsi for
doing various fixups, and uses this to correct the modeline.
v2:
- s/mode_fixup/dmi_quirk/ to make the new DMI quirk mechanism more generic
- Add a comment with the old and new modelines to the patch and commit msg
v3:
- Add Closes tag to gitlab issue with drm.debug=0xe, VBT info
