Hi,

FYI, your patch has been queued to stable release 24.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/13/26. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/45d35d5f7b2d5f3d9f6e00d56ef70333a5ddb5ec

Thanks.

Luca Boccassi

Subject: [PATCH] examples/vm_power_manager: fix const discarding

[ upstream commit 629d136b2501aabb85a49205c049f71ed170c790 ]

When compiling with GCC 15.2.1, a const qualifier issue
is seen with this warning:

In function 'get_resource_name_from_chn_path':
examples/vm_power_manager/channel_monitor.c:139:16:
error: assignment discards 'const' qualifier from pointer target type
  139 | substr = strstr(channel_path, CHANNEL_MGR_FIFO_PATTERN_NAME);
      |        ^

The function get_resource_name_from_chn_path is used only once
and call a single function (strstr),
so it can be replaced with a direct call to strstr().

Fixes: 221e7026d521 ("examples/power: add FIFO per core for JSON interface")
