patch 'net/qede/base: fix 32-bit build with GCC 12' has been queued to stable release 19.11.14

[christian.ehrhardt at canonical.com]

Hi,

FYI, your patch has been queued to stable release 19.11.14

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/18/22. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/8f270efdacb9b579514fa2493689cc11f45d1f5f

Thanks.

[ upstream commit acc0ed087cd1ce6464f63489ab17eca52b0c94b2 ]

A pointer is passed to a macro and it seems mistakenly referenced.
This issue is seen only when compiling with GCC 12 for 32-bit:

drivers/net/qede/base/ecore_init_fw_funcs.c:1418:25:
        error: array subscript 1 is outside array bounds of ‘u32[1]’
        {aka ‘unsigned int[1]’} [-Werror=array-bounds]
 1418 |                 ecore_wr(dev, ptt, ((addr) + (4 * i)),  \
      |                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 1419 |                          ((u32 *)&(arr))[i]);           \

drivers/net/qede/base/ecore_init_fw_funcs.c:1465:17:
        note: in expansion of macro ‘ARR_REG_WR’
 1465 |         ARR_REG_WR(p_hwfn, p_ptt, addr, pData, len_in_dwords);
      |         ^~~~~~~~~~
drivers/net/qede/base/ecore_init_fw_funcs.c:1439:35:
        note: at offset 4 into object ‘pData’ of size 4
 1439 |                              u32 *pData,
      |                              ~~~~~^~~~~
