ASoC: starfive/jh7110-pwmdac: Convert to platform remove callback returning void

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

net: stmmac: xgmac: use #define for string constants

commit 1692b9775e745f84b69dc8ad0075b0855a43db4e upstream.

The cited commit introduces and uses the string constants dpp_tx_err and
dpp_rx_err. These are assigned to constant fields of the array
dwxgmac3_error_desc.

It has been reported that on GCC 6 and 7.5.0 this results in warnings
such as:

  .../dwxgmac2_core.c:836:20: error: initialiser element is not constant
   { true, "TDPES0", dpp_tx_err },

I have been able to reproduce this using: GCC 7.5.0, 8.4.0, 9.4.0 and 10.5.0.
But not GCC 13.2.0.

So it seems this effects older compilers but not newer ones.
As Jon points out in his report, the minimum compiler supported by
the kernel is GCC 5.1, so it does seem that this ought to be fixed.

It is not clear to me what combination of 'const', if any, would address
this problem.  So this patch takes of using #defines for the string
constants

Compile tested only.

io_uring/net: limit inline multishot retries

Commit 76b367a2d83163cf19173d5cb0b562acbabc8eac upstream.

If we have multiple clients and some/all are flooding the receives to
such an extent that we can retry a LOT handling multishot receives, then
we can be starving some clients and hence serving traffic in an
imbalanced fashion.

Limit multishot retry attempts to some arbitrary value, whose only
purpose serves to ensure that we don't keep serving a single connection
for way too long. We default to 32 retries, which should be more than
enough to provide fairness, yet not so small that we'll spend too much
time requeuing rather than handling traffic.

io_uring/poll: add requeue return code from poll multishot handling

Commit 704ea888d646cb9d715662944cf389c823252ee0 upstream.

Since our poll handling is edge triggered, multishot handlers retry
internally until they know that no more data is available. In
preparation for limiting these retries, add an internal return code,
IOU_REQUEUE, which can be used to inform the poll backend about the
handler wanting to retry, but that this should happen through a normal
task_work requeue rather than keep hammering on the issue side for this
one request.

No functional changes in this patch, nobody is using this return code
just yet.

In preparation for putting some retry logic in there, have the done
path just skip straight to the end rather than have too much nesting
in here.
