Currently each channel is added as list to dai channel list, however
there is danger of adding same channel to multiple dai channel list
which endups corrupting the other list where its already added.
This patch ensures that the channel is actually free before adding to

before deleting it.

This is because there is no associated iommu_group with the device. The

device_add() via the platform bus:

Fix this bugs by adding checks about ctx[0] and ctx[1].
This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or

With both integrated and discrete Intel GPUs in a system, the current
global check of intel_iommu_gfx_mapped, as done from intel_vtd_active()
may not be completely accurate.
In this patch we add i915 parameter to intel_vtd_active() in order to
prepare it for multiple GPUs and we also change the check away from Intel
specific intel_iommu_gfx_mapped (global exported by the Intel IOMMU
driver) to probing the presence of IOMMU on a specific device using
device_iommu_mapped().
This will return true both for IOMMU pass-through and address translation
modes which matches the current behaviour. If in the future we wanted to
distinguish between these two modes we could either use
iommu_get_domain_for_dev() and check for __IOMMU_DOMAIN_PAGING bit
indicating address translation, or ask for a new API to be exported from
the IOMMU core code.

While working on supporting the Intel HDR backlight interface, I noticed
that there's a couple of laptops that will very rarely manage to boot up
without detecting Intel HDR backlight support - even though it's supported
on the system. One example of such a laptop is the Lenovo P17 1st
generation.
Following some investigation Ville Syrjälä did through the docs they have
available to them, they discovered that there's actually supposed to be a
30ms wait after writing the source OUI before we begin setting up the rest
of the backlight interface.
This seems to be correct, as adding this 30ms delay seems to have
completely fixed the probing issues I was previously seeing. So - let's
start performing a 30ms wait after writing the OUI, which we do in a manner
similar to how we keep track of PPS delays (e.g. record the timestamp of
the OUI write, and then wait for however many ms are left since that
timestamp right before we interact with the backlight) in order to avoid
waiting any longer then we need to. As well, this also avoids us performing
this delay on systems where we don't end up using the HDR backlight
interface.

* Move last_oui_write into intel_dp

The device health recovery flow calls mlx5_health_wait_pci_up() which
queries the device for FW_RESET timeout after freeing the device
timeouts structure on mlx5_function_teardown(). Fix this bug by moving
timeouts structure init/cleanup to the device's init/uninit phases.
Since it is necessary to reset default software timeouts on function
reload, extract setting of defaults values from mlx5_tout_init() and
call mlx5_tout_set_def_val() directly from mlx5_function_setup().

When adding rule with multiple destinations, indirect table is used for all of
the destinations if at least one of the destinations support it, this can cause
creation of invalid indirect tables for the destinations that doesn't support it.
Fixed it by using indirect table only if all destinations support it.

Always use MLX5_FLOW_TABLE_OTHER_VPORT flag when creating egress ACL
table for single FDB. Not doing so on BlueField will make firmware fail
the command. On BlueField the E-Switch manager is the ECPF (vport 0xFFFE)
which is filled in the flow table creation command but as the
other_vport field wasn't set the firmware complains about a bad parameter.
This is different from a regular HCA where the E-Switch manager vport is
the PF (vport 0x0). Passing MLX5_FLOW_TABLE_OTHER_VPORT will make the
firmware happy both on BlueField and on regular HCAs without special
condition for each.
This fixes the bellow firmware syndrome:
mlx5_cmd_check:819:(pid 571): CREATE_FLOW_TABLE(0x930) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x754a4)

To enable transmit schduler on vport FW require non-zero configuration
for vport's TSAR. If vport added to the group which has configured BW
share value and TX rate values of the vport are zero, then scheduler
wouldn't be enabled on this vport.
Fix that by calling BW normalization if BW share of the new group is
configured.
