Sorry I did not notice this patch and I recently submitted one
which I will abandon.
It seems there was no reply from qede maintainers after 6 weeks,
but I will apply anyway.
I will use my commit message:
net/qede/base: fix 32-bit build with GCC 12
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:

1439 | u32 *pData,
