patch 'bus/dpaa: remove unused variable' has been queued to stable release 24.11.9

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 24.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/26. 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/ee2bedacc3c0c50a866c967ae213a61ffc31a0a4

Thanks.

Luca Boccassi

Subject: [PATCH] bus/dpaa: remove unused variable

[ upstream commit 030565d82a78b400a0be4dcdbc6561572d49857b ]

The driver was recording the clock frequency and never using it.

clang 23 reports:

  qman_driver.c:27:12: warning: variable 'qman_clk' set but not used
        [-Wunused-but-set-global]

Remove the variable and the dead store.

Fixes: f6fadc3e6310 ("bus/dpaa: add QMAN interface driver")
