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.

Assign all possible fields of pinfo in variable declaration, instead of
just zeroing it there.

vsc_tp_wakeup_request() called wait_event_timeout() with
gpiod_get_value_cansleep() which may sleep, and does so as the
implementation is that of gpio-ljca.
Move the GPIO state check outside the call.

The hard IRQ handler vsc_tp_irq() is called with a raw spinlock taken.
wake_up() acquires a spinlock, a sleeping lock on PREEMPT_RT. This leads
to sleeping in atomic context.
Move the wake_up() call to the threaded IRQ handler vsc_tp_thread_isr()
where it can be safely called.

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.
