spi: make remove callback a void function
Merge series from Uwe Kleine-König <u.kleine-koenig@pengutronix.de>:

this series goal is to change the spi remove callback's return value to void.
After numerous patches nearly all drivers already return 0 unconditionally.
The four first patches in this series convert the remaining three drivers to
return 0, the final patch changes the remove prototype and converts all
implementers.

bf3608f338 hwmon: peci: Add cputemp driver
Add peci-cputemp driver for Digital Thermal Sensor (DTS) thermal
readings of the processor package and processor cores that are
accessible via the PECI interface.

The main use case for the driver (and PECI interface) is out-of-band
management, where we're able to obtain the DTS readings from an external
entity connected with PECI, e.g. BMC on server platforms.

6523d3b2ff peci: Add core infrastructure
Intel processors provide access for various services designed to support
processor and DRAM thermal management, platform manageability and
processor interface tuning and diagnostics.
Those services are available via the Platform Environment Control
Interface (PECI) that provides a communication channel between the
processor and the Baseboard Management Controller (BMC) or other
platform management device.

This change introduces PECI subsystem by adding the initial core module
and API for controller drivers.

db405774f6 MAINTAINERS: Add entry for fbdev core
Ever since Tomi extracted the core code in 2014 it's been defacto me
maintaining this, with help from others from dri-devel and sometimes
Linus (but those are mostly merge conflicts):

$ git shortlog -ns  drivers/video/fbdev/core/ | head -n5
    35  Daniel Vetter
    23  Linus Torvalds
    10  Hans de Goede
     9  Dave Airlie
     6  Peter Rosin

I think ideally we'd also record that the various firmware fb drivers
(efifb, vesafb, ...) are also maintained in drm-misc because for the
past few years the patches have either been to fix handover issues
with drm drivers, or caused handover issues with drm drivers. So any
other tree just doesn't make sense. But also, there's plenty of
outdated MAINTAINER entries for these with people and git trees that
haven't been active in years, so maybe let's just leave them alone.
And furthermore distros are now adopting simpledrm as the firmware fb
driver, so hopefully the need to care about the fbdev firmware drivers
will go down going forward.

Note that drm-misc is group maintained, I expect that to continue like
we've done before, so no new expectations that patches all go through
my hands. That would be silly. This also means I'm happy to put any
other volunteer's name in the M: line, but otherwise git log says I'm
the one who's stuck with this.

7938f42181 dma-buf-map: Rename to iosys-map
Rename struct dma_buf_map to struct iosys_map and corresponding APIs.
Over time dma-buf-map grew up to more functionality than the one used by
dma-buf: in fact it's just a shim layer to abstract system memory, that
can be accessed via regular load and store, from IO memory that needs to
be acessed via arch helpers.

The idea is to extend this API so it can fulfill other needs, internal
to a single driver. Example: in the i915 driver it's desired to share
the implementation for integrated graphics, which uses mostly system
memory, with discrete graphics, which may need to access IO memory.

The conversion was mostly done with the following semantic patch:

	@r1@
	@@
	- struct dma_buf_map
	+ struct iosys_map

	@r2@
	@@
	(
	- DMA_BUF_MAP_INIT_VADDR
	+ IOSYS_MAP_INIT_VADDR
	|
	- dma_buf_map_set_vaddr
	+ iosys_map_set_vaddr
	|
	- dma_buf_map_set_vaddr_iomem
	+ iosys_map_set_vaddr_iomem
	|
	- dma_buf_map_is_equal

Then some files had their includes adjusted and some comments were
update to remove mentions to dma-buf-map.

Since this is not specific to dma-buf anymore, move the documentation to
the "Bus-Independent Device Accesses" section.

v2:
  - Squash patches

v3:
  - Fix wrong removal of dma-buf.h from MAINTAINERS
  - Move documentation from dma-buf.rst to device-io.rst

v4:
  - Change documentation title and level

There are a few different places where pahole's version is turned into a
three digit form with the exact same command. Move this command into
scripts/pahole-version.sh to reduce the amount of duplication across the

Create CONFIG_PAHOLE_VERSION so the version code can be used in Kconfig
to enable and disable configuration options based on the pahole version,
which is already done in a couple of places.

dt-bindings: display: Turn lvds.yaml into a generic schema
The lvds.yaml file so far was both defining the generic LVDS properties
(such as data-mapping) that could be used for any LVDS sink, but also
the panel-lvds binding.

That last binding was to describe LVDS panels simple enough, and had a
number of other bindings using it as a base to specialise it further.

However, this situation makes it fairly hard to extend and reuse both
the generic parts, and the panel-lvds itself.

Let's remove the panel-lvds parts and leave only the generic LVDS
properties.
