Termination of Immediate Notify IOCB was using wrong
IOCB handle. IOCB completion code was unable to find
appropriate code path due to wrong handle.

During code inspection, while investigating following stack trace
seen on one of the test setup, we found out there was possibility
of memory leak becuase driver was not unwinding the stack properly.
This issue has not been reproduced in a test environment or on a
customer setup.
Here's stack trace that was seen.

The function stmmac_dt_phy provides several possibilities for initializing
plat->mdio_node, all of which have the effect of increasing the reference
count of the assigned value. This field is not updated elsewhere, so the
value is live until the end of the lifetime of plat (devm_allocated), just
after the end of stmmac_remove_config_dt. Thus, add an of_node_put on
plat->mdio_node in stmmac_remove_config_dt. It is possible that the field
mdio_node is never initialized, but of_node_put is NULL-safe, so it is also
safe to call of_node_put in that case.

Zoned block devices force the use of READ/WRITE(16) commands by setting
sdkp->use_16_for_rw and clearing sdkp->use_10_for_rw. This result in
DPOFUA always being disabled for these drives as the assumed use of
the deprecated READ/WRITE(6) commands only looks at sdkp->use_10_for_rw.
Strenghten the test by also checking that sdkp->use_16_for_rw is false.

7) Do not use kernel stack for DMA buffers in atusb driver, from Stefan
Schmidt.
8) Openvswitch conntack actions need to maintain a correct checksum,

9) ax25_disconnect() is missing a check for ax25->sk being NULL, in
fact it already checks this, but not in all of the necessary spots.

10) Action GET operations in the packet scheduler can erroneously bump

We wouldn't normally expect ops->attach_dev() to fail, but on IOMMUs
with limited hardware resources, or generally misconfigured systems,
it is certainly possible. We report failure correctly from the external
iommu_attach_device() interface, but do not do so in iommu_group_add()
when attaching to the default domain. The result of failure there is
that the device, group and domain all get left in a broken,
part-configured state which leads to weird errors and misbehaviour down
the line when IOMMU API calls sort-of-but-don't-quite work.
Check the return value of __iommu_attach_device() on the default domain,
and refactor the error handling paths to cope with its failure and clean
up correctly in such cases.
