76f0c82446 media: ov5693: Improve error logging when fwnode is not found
The ov5693 driver waits for the endpoint fwnode to show up in case this
fwnode is created by a bridge-driver.

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] i2c i2c-INT33BE:00: 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 fwnode graph endpoint

Also update the comment to not refer to the no longer existing cio2-bridge
code.

0c92c49fc6 media: ivsc: Fix crash at shutdown due to missing mei_cldev_disable() calls
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:

5a0400aca5 media: v4l2-ctrls: Don't reset handler's error in v4l2_ctrl_handler_free()
It's a common pattern in drivers to free the control handler's resources
and then return the handler's error code on drivers' error handling paths.
Alas, the v4l2_ctrl_handler_free() function also zeroes the error field,
effectively indicating successful return to the caller.

There's no apparent need to touch the error field while releasing the
control handler's resources and cleaning up stale pointers. Not touching
the handler's error field is a more certain way to address this problem
than changing all the users, in which case the pattern would be likely to
re-emerge in new drivers.

Do just that, don't touch the control handler's error field in
v4l2_ctrl_handler_free().

get_frame_interval/set_frame_interval causes a deadlock, as the
subdev state is locked in the [1] but also in the driver itself.

In [2] it's described that the caller is responsible to acquire and
release the lock in this case. Therefore, acquiring the lock in the
driver is wrong.

Remove the lock acquisitions/releases from mt9m114_ifp_get_frame_interval()
and mt9m114_ifp_set_frame_interval().

208119b4a1 media: mt9m114: Bypass PLL if required
The MT9M114 sensor has an internal PLL that generates the required SYSCLK
from EXTCLK. It also has the option to bypass the PLL and use EXTCLK
directly as SYSCLK.
The current driver implementation uses a hardcoded PLL configuration that
requires a specific EXTCLK frequency. Depending on the available clocks,
it can be desirable to use a different PLL configuration or to bypass it.

The link-frequency of the output bus (Parallel or MIPI-CSI) is configured
in the device tree.

Check if EXTCLK can be used as SYSCLK to achieve this link-frequency. If
yes, bypass the PLL.
Otherwise, (as before) check if EXTCLK and the default PLL configuration
provide the required SYSCLK to achieve the link-frequency. If yes, use the
PLL. If no, throw an error.

In the case where buffer[i] is 500000, idata->freq overflows the u32
multiplication for any values >= 8590.

0xFFFFFFFF / 500000 ~= 8589

By casting buffer[i] to u64, idata->freq can be any u32 value without
overflowing the multiplication.

0xFFFFFFFFFFFFFFFF / 500000 ~= 36893488147419 (> 4294967295)

The result of the final operation will fit back into the unsigned int
limits without any issues.

500000 * 0xFFFFFFFF / 1000000 = 0x80000000 (< 0xFFFFFFFF)

032a68ccb7 media: rc: ir-spi: constrain carrier frequency
Carrier frequency is currently unconstrained, allowing the SPI transfer
to be allocated and filled only for it to be later rejected by the SPI
controller since the frequency is too large.

Add a check to constrain the carrier frequency inside
ir_spi_set_tx_carrier().

Also, move the number of bits per pulse to a macro since it is not used
in multiple places.

Replace the static transmit buffer with a dynamically allocated one,
removing the limit imposed on the number of pulses to transmit.

Calculate the number of pulses for each duration in the received buffer
ahead of time, while also adding up the total pulses, to be able to

ff8c5622f9 media: rkvdec: Restore iommu addresses on errors
On errors, the rkvdec chip self resets. This can clear the addresses
programmed in the iommu. This case is signaled by the
RKVDEC_SOFTRESET_RDY status bit.

Since the iommu framework does not have a restore functionality, and
as recommended by the iommu subsystem maintainers, this patch
restores the iommu programming by attaching and detaching an empty
domain, which will clear and restore the default domain.
