Could you also push v5.10.214-rt106-rebase tag to the repository for

Ok, let me convert the non-error ones to dev_dbg() and split the long
lines. Debug needs to be enabled, so it should not bother anyone, and
it is easier than refactoring driver to use debugfs.

Yep, I fought with device trees for few days. I should have yaml

Thanks for the review. Fixing checkpatch issues is easy, but it looks
like closer look will be needed at the devicetree probing.
Also, what are the authors preferences about the license? I'd prefer

y don't want that to run with clock being disabled and DMA
being unmapped.
We certainly don't want phy_disconnect() being undone by
phy_connect_direct() running in the workqueue.
IOW this patch is not enough to fix the bugs, and at least fix below
is needed to get something reasonable.

Ok, it's really fancy, we add task_work with TWA_SIGNAL to a guaranteed
not exited/exec task, it succeeds, but the
on the mapping
it is executing from.
The makes no difference yet as the relocation code runs with the MMU

of this type
will be represented as signed integer.
type = nla_get_u32(info->attrs[NL802154_ATTR_IFTYPE]);
u32 will be casted to signed, which can cause negative value type.

Yeah, but it should not leak the PM reference in the error handling.

ok at the goto. Does not need to be there.
Second check the crazy calling convention. If nic_start() fails, it
should clean up after itself.
Then, check the code. nic_stop() undoes initialization that was not
even done in the nic_start().
This introduces more problems than it solves.
