Subject: [PATCH] net/qede/base: fix 32-bit build with GCC 12
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
[ 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,
