eth: bnxt: fix one of the W=1 warnings about fortified memcpy()
Fix a W=1 warning with gcc 13.1:
In function ‘fortify_memcpy_chk’,
inlined from ‘bnxt_hwrm_queue_cos2bw_cfg’ at drivers/net/ethernet/broadcom/bnxt/bnxt_dcb.c:133:3:
include/linux/fortify-string.h:592:25: warning: call to ‘__read_overflow2_field’ declared with attribute warning: detected read beyond size of field (2nd parameter); maybe use struct_group()? [-Wattribute-warning]
592 | __read_overflow2_field(q_size_field, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The field group is already defined and starts at queue_id:
struct bnxt_cos2bw_cfg {
u8 pad[3];
struct_group_attr(cfg, __packed,
u8 queue_id;
__le32 min_bw;
