When adding a new fd to an epoll, and that this new fd is an
epoll fd itself, we recursively scan the fds attached to it
to detect cycles, and add non-epool files to a "check list"
that gets subsequently parsed.
However, this check list isn't completely safe when deletions
can happen concurrently. To sidestep the issue, make sure that
a struct file placed on the check list sees its f_count increased,
ensuring that a concurrent deletion won't result in the file
disapearing from under our feet.

Currently the nexthop code will use an empty NHA_GROUP attribute, but it
requires at least 1 entry in order to function properly. Otherwise we
end up derefencing null or random pointers all over the place due to not
having any nh_grp_entry members allocated, nexthop code relies on having at
least the first member present. Empty NHA_GROUP doesn't make any sense so
just disallow it.
Also add a WARN_ON for any future users of nexthop_create_group().

The patch reorganizing the set_freq function made it so the gmu resume
doesn't always set the frequency, because a6xx_gmu_set_freq() exits early
when the frequency hasn't been changed. Note this always happens when
resuming GMU after recovering from a hang.
Use a simple workaround to prevent this from happening.

One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable structure in the iio_priv() data.
This data is allocated with kzalloc so no data can leak apart from
previous readings.
The explicit alignment of ts is not necessary in this case as by
coincidence the padding will end up the same, however I consider
it to make the code less fragile and have included it.

The kernel fails to compile due to undefined reference to
devm_iio_triggered_buffer_setup() if IIO_TRIGGERED_BUFFER is not
enabled. The original patch [1] had this dependency. But somehow it
didn't make it into the kernel tree. Re-add it.

To stop conversion ads1015_set_power_state() function call unimplemented
function __pm_runtime_suspend() from pm_runtime_put_autosuspend()
if CONFIG_PM is not set.
In case of CONFIG_PM is not set: __pm_runtime_suspend() returns -ENOSYS,
so ads1015_read_raw() failed because ads1015_set_power_state() returns an
error.
If CONFIG_PM is disabled, there is no need to start/stop conversion.
Fix it by adding return 0 function variant if CONFIG_PM is not set.

The null check on a failed workqueue create is currently null checking
hdev->cq_wq rather than the pointer hdev->cq_wq[i] and so the test
will never be true on a failed workqueue create. Fix this by checking

In Gaudi, the default max power setting is different between PCI and PMC
cards. Therefore, the driver need to set the default after knowing what is
the card type.
The current code has a bug where it limits the maximum power of the PMC
card to 200W after a reset occurs.
