Pull char/misc and other driver subsystem updates from Greg KH:
"Here is the big set of char/misc and a number of other driver
subsystem updates for 6.9-rc1. Included in here are:
- IIO driver updates, loads of new ones and evolution of existing ones
- coresight driver updates
- const cleanups for many driver subsystems
- speakup driver additions
- platform remove callback void cleanups
- mei driver updates
- mhi driver updates
- cdx driver updates for MSI interrupt handling
- nvmem driver updates
- other smaller driver updates and cleanups, full details in the
shortlog
All of these have been in linux-next for a long time with no reported
issue, other than a build warning for the speakup driver"
The build warning hits clang and is a gcc (and C23) extension, and is
fixed up in the merge.

On Arrow Lake S systems, MEI is no longer strictly connected to bus 0,
while graphics remain exclusively on bus 0. Adapt the component
matching logic to accommodate this change:
Original behavior: Required both MEI and graphics to be on the same
bus 0.
New behavior: Only enforces graphics to be on bus 0 (integrated),
allowing MEI to reside on any bus.
This ensures compatibility with Arrow Lake S and maintains functionality
for the legacy systems.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The dependencies in the mei framework are inconsistent, with some symbols
using 'select INTEL_MEI' to force it being enabled and others using
'depends on INTEL_MEI'.
In general, one should not select user-visible symbols, so change all
of these to normal dependencies, but change the default on INTEL_MEI to
be enabled when building a kernel for an Intel CPU with ME or a generic
x86 kernel.
Having consistent dependencies makes the 'menuconfig' listing more
readable by using proper indentation.
A large if/endif block is just a simpler syntax than repeating the
dependencies for each symbol.

CONFIG_INTEL_MEI_VSC_HW can be set to built-in even with CONFIG_MEI=m,
but then the driver is not built because Kbuild never enters the
drivers/misc/mei directory for built-in files, leading to a link

Add an explicit dependency on CONFIG_MEI that was apparently missing,
to ensure the VSC_HW driver cannot be built-in with MEI itself being
a loadable module.

The Intel visual sensing controller (IVSC) device is designed to control
the camera sharing between host IPU for media usage and IVSC for context
sensing (face detection).
IVSC is exposed to HOST as an SPI device and the message protocol over
the SPI BUS for communicating with the IVSC device is implemented. This
is the backend of mei framework for IVSC device, which usually handles
the hardware data transfer. The mei_csi and mei_ace are the clients of
IVSC mei framework.
The firmware downloading for the IVSC device is implemented as well.

GSC devices perform legal firmware initiated resets due to state transition
that may appear as unexpected to the driver. Lower the log level for those
devices to debug level and save the firmware status registers.
When the device comes out of the reset it is possible to check whether the
resets was due to a firmware error or an exception
and only than produce a warning.
