When build wifi driver based on next-20230119 Linux code, will observe
the following build errors.
/mwifiex/mxm_wifiex/wlan_src/mlinux/moal_eth_ioctl.c: In function ‘woal_priv_get_ap’:
/mwifiex/mxm_wifiex/wlan_src/mlinux/moal_eth_ioctl.c:5968:39: error: invalid application of ‘sizeof’ to incomplete type ‘char[]’
5968 | sizeof(mwr->u.ap_addr.sa_data));
| ^
make[2]: *** [scripts/Makefile.build:252: /work/mwifiex/mxm_wifiex/wlan_src/mlinux/moal_eth_ioctl.o] Error 1
make[1]: *** [Makefile:2027: /work/mwifiex/mxm_wifiex/wlan_src] Error 2
make[1]: Leaving directory '/work/linux-nxp-rebase'
This is caused by kernel patch b5f0de6df6dc("net: dev: Convert sa_data
to flexible array in struct sockaddr"), now anything using
sizeof(sa->sa_data) must switch to sizeof(sa->sa_data_min).
