The conversion of all GPIO drivers to using the .set_rv() and
.set_multiple_rv() callbacks from struct gpio_chip (which - unlike their
predecessors - return an integer and allow the controller drivers to
indicate failures to users) is now complete and the legacy ones have
been removed. Rename the new callbacks back to their original names in
one sweeping change.

The ipu-bridge code waits for the IVSC to become ready (on platforms with
an IVSC chip).
It does this by returning -EPROBE_DEFER, but it does not use
dev_err_probe() so no reason for deferring gets registered.
After 30 seconds the kernel logs a warning that the probe is still
deferred, which looks like this:
[ 33.951709] pci 0000:00:14.3: deferred probe pending: (reason unknown)
Use dev_err_probe() when returning -EPROBE_DEFER to register the probe
deferral reason changing the error to:
deferred probe pending: waiting for IVSC to become ready
to help with debugging why drivers are not binding if the iVSC does
not become ready for some reason.

Both the ACE and CSI driver are missing a mei_cldev_disable() call in
their remove() function.
This causes the mei_cl client to stay part of the mei_device->file_list
list even though its memory is freed by mei_cl_bus_dev_release() calling
kfree(cldev->cl).
This leads to a use-after-free when mei_vsc_remove() runs mei_stop()
which first removes all mei bus devices calling mei_ace_remove() and
mei_csi_remove() followed by mei_cl_bus_dev_release() and then calls
mei_cl_all_disconnect() which walks over mei_device->file_list dereferecing
the just freed cldev->cl.
And mei_vsc_remove() it self is run at shutdown because of the
platform_device_unregister(tp->pdev) in vsc_tp_shutdown()
When building a kernel with KASAN this leads to the following KASAN report:
