ERR_PTR(). The IS_ERR() test in the return value check should be

While fixing another issue in this driver I noticed it uses
IS_ERR_OR_NULL(), which is almost always a mistake.
Change the driver to use the proper devm_reset_control_get_optional()
interface instead and remove the checks except for the one that
checks for a failure in that function.

The driver was issuing synchronous uninterruptible control requests
without using a timeout. This could lead to the driver hanging on probe
due to a malfunctioning (or malicious) device until the device is
physically disconnected. While sleeping in probe the driver prevents
other devices connected to the same hub from being added to (or removed
from) the bus.
The USB upper limit of five seconds per request should be more than
enough.

The F54 Report Data is apparently read through a fifo and for
the smbus protocol that means that between reading a block of 32
bytes the rmiaddr shouldn't be incremented. However, changing
that causes other non-fifo reads to fail and so that change was
reverted.
This patch changes just the F54 function and it now reads 32 bytes
at a time from the fifo, using the F54_FIFO_OFFSET to update the
start address that is used when reading from the fifo.
This has only been tested with smbus, not with i2c or spi. But I
suspect that the same is needed there since I think similar
problems will occur there when reading more than 256 bytes.

This reverts commit a284e11c371e446371675668d8c8120a27227339.
This causes problems (drifting cursor) with at least the F11 function that
reads more than 32 bytes.
The real issue is in the F54 driver, and so this should be fixed there, and
not in rmi_smbus.c.
So first revert this bad commit, then fix the real problem in F54 in another
patch.

Since the bulk queue used by XDP_REDIRECT now lives in struct net_device,
we can re-use the bulking for the non-map version of the bpf_redirect()
helper. This is a simple matter of having xdp_do_redirect_slow() queue the
frame on the bulk queue instead of sending it out with __bpf_tx_xdp().
Unfortunately we can't make the bpf_redirect() helper return an error if
the ifindex doesn't exit (as bpf_redirect_map() does), because we don't
have a reference to the network namespace of the ingress device at the time
the helper is called. So we have to leave it as-is and keep the device
lookup in xdp_do_redirect_slow().
Since this leaves less reason to have the non-map redirect code in a
separate function, so we get rid of the xdp_do_redirect_slow() function
entirely. This does lose us the tracepoint disambiguation, but fortunately
the xdp_redirect and xdp_redirect_map tracepoints use the same tracepoint
entry structures. This means both can contain a map index, so we can just
amend the tracepoint definitions so we always emit the xdp_redirect(_err)
tracepoints, but with the map ID only populated if a map is present. This
means we retire the xdp_redirect_map(_err) tracepoints entirely, but keep
the definitions around in case someone is still listening for them.
With this change, the performance of the xdp_redirect sample program goes
from 5Mpps to 8.4Mpps (a 68% increase).
Since the flush functions are no longer map-specific, rename the flush()
functions to drop _map from their names. One of the renamed functions is
the xdp_do_flush_map() callback used in all the xdp-enabled drivers. To
keep from having to update all drivers, use a #define to keep the old name
working, and only update the virtual drivers in this patch.

Devicetrees.
- Move of two device nodes that got applied to the wrong part of the

- Regulator fix for Beaglebone X15 (adding 12/5V supplies)
- Use interrupts for keys on Amlogic SM1 to avoid missed polls
In addition to that, there is a collection of smaller DT fixes:
- Power supply assignment fixes for i.MX6
- Fix of interrupt line for magnetometer on i.MX8 Librem5 devkit
- Build fixlets (selects) for davinci/omap2+
- More interrupt number fixes for Stratix10, Amlogic SM1, etc.
- ... and more similar fixes across different platforms
And some non-DT stuff:
- optee fix to register multiple shared pages properly
- Clock calculation fixes for MMP3
- Clock fixes for OMAP as well"

Increase the number of chains and priorities to support
the whole range available in tc.
We use unmanaged tables and ignore flow level to create more
tables than what we declared to fs_core steering, and we manage
the connections between the tables themselves.
To support that we need FW with ignore_flow_level capability.
Otherwise the old behaviour will be used, where we are limited
by the number of levels we declared (4 chains, 16 prios).

Currently, Most of the steering tree is statically declared ahead of time,
with steering prios instances allocated for each fdb chain to assign max
number of levels for each of them. This allows fs_core to manage the
connections and levels of the flow tables hierarcy to prevent loops, but
restricts us with the number of supported chains and priorities.
Introduce unmananged flow tables, allowing the user to manage the flow
table connections. A unamanged table is detached from the fs_core flow
table hierarcy, and is only connected back to the hierarchy by explicit
FTEs forward actions.
This will be used together with firmware that supports ignoring the flow
table levels to increase the number of supported chains and prios.

Currently the property entry kunit tests are built if CONFIG_KUNIT=y.
This will cause warnings when merged with the kunit tree that now
supports tristate CONFIG_KUNIT. While the tests appear to compile
as a module, we get a warning about missing module license.
It's better to have a per-test suite CONFIG variable so that
we can do selective building of kunit-based suites, and can
also avoid merge issues like this.

These normal volumes should be freed through kill_volumes() and

Add counters that count (per priority) the number of received
packets that dropped due to lack of buffers on a physical port. If
this counter is increasing, it implies that the adapter is
congested and cannot absorb the traffic coming from the network.

In procedure mlx4_ib_add_gid(), if the driver is unable to update the FW
gid table, there is a memory leak in the driver's copy of the gid table:
the gid entry's context buffer is not freed.
If such an error occurs, free the entry's context buffer, and mark the
entry as available (by setting its context pointer to NULL).

When mac80211 ask for a frame to be sent after a DTIM, driver should:
1. Update TIM with multicast bit set (using update_ie). This function
can be called whenever.
2. Keep buffered all frames marked "after dtim"
3. When it receive a suspend_resume indication (see
wfx_suspend_resume_mc()), send all the buffered frames. This
indication is sent by the firmware 4ms before the dtim.
4. If one of the frames returns status "REQUEUE", it means that the
DTIM period was ended before to be able to send the frame.
5. When all the buffered frames were sent or if DTIM period was ended,
driver should update the TIM with multicast bit reset.
All the mess with the asynchronous works can be dropped.

Indeed, it is not necessary to pass whole hif_ind_suspend_resume_tx to
wfx_suspend_resume_mc().
In add, the structure hif_ind_suspend_resume_tx come from hardware API.
It is not intended to be manipulated in upper layers of the driver.

At the beginning, firmware could send suspend_resume indication to
notify that a station wake up or sleep down. However, mac80211 already
handles power save status of stations and this behavior has been removed
from the firmware. So now, when suspend_resume indication is received,
it is always to notify that a DTIM is about to be sent.
So, it is possible to simply wfx_suspend_resume().
