The ice_get_vf_vsi function can return NULL in some cases, such as if
handling messages during a reset where the VSI is being removed and
recreated.
Several places throughout the driver do not bother to check whether this
VSI pointer is valid. Static analysis tools maybe report issues because
they detect paths where a potentially NULL pointer could be dereferenced.
Fix this by checking the return value of ice_get_vf_vsi everywhere.

Switch id should be the same for each netdevice on a driver.
The id must be unique between devices on the same system, but
does not need to be unique between devices on different systems.
The switch id is used to locate ports on a switch and to know if
aggregated ports belong to the same switch.
To meet this requirements, use pci_get_dsn as switch id value, as
this is unique value for each devices on the same system.
Implementing switch id is needed by automatic tools for kubernetes.
Set switch id by setting devlink port attribiutes and calling
devlink_port_attrs_set while creating pf (for uplink) and vf
(for representator) devlink port.

We need to start parsing stuff from the tail end of the LFP data block.
This is made awkward by the fact that the fp_timing table has variable
size. So we must use a bit more finesse to get the tail end, and to
make sure we allocate enough memory for it to make sure our struct
representation fits.

Modern VBTs no longer contain the LFP data table pointers
block (41). We are expecting to have one in order to be able
to parse the LFP data block (42), so let's make one up.
Since the fp_timing table has variable size we must somehow
determine its size. Rather than just hardcode it we look for
the terminator bytes (0xffff) to figure out where each table
entry starts. dvo_timing, panel_pnp_id, and panel_name are
expected to have fixed size.
This has been observed on various machines, eg. TGL with BDB
version 240, CML with BDB version 231, etc. The most recent
VBT I've observed that still had block 41 had BDB version
228. So presumably the cutoff (if an exact cutoff even exists)
is somewhere around BDB version 229-231.

Due to the difference between IPC3 and IPC4 messaging we need to introduce new

kept as they were and leaving it for the IPC specific code to handle the
differences.
The series provides the foundation for both lowe level (sound/soc/sof/intel) and

Since the introduction of regulator->enable_count, a driver that did
an exclusive get on an already-enabled regulator would end up with
enable_count initialized to 0 but rdev->use_count initialized to 1.
With that starting point the regulator is effectively stuck enabled,
because if the driver attempted to disable it it would fail the
enable_count underflow check in _regulator_handle_consumer_disable().
The EXCLUSIVE_GET path in _regulator_get() now initializes
enable_count along with rdev->use_count so that the regulator can be
disabled without underflowing the former.
