Hi Christophe,
Unfortunately allmodconfig W=1 build on x86_64 with Clang says:
.../libipw_wx.c:587:6: error: assigning to 'struct lib80211_crypto_ops *' from 'const struct lib80211_crypto_ops *' discards qualifiers [-Werror,-Wincompatible-pointer-types-discards-qualifiers]
587 | ops = lib80211_get_crypto_ops(alg);
| ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.../libipw_wx.c:590:7: error: assigning to 'struct lib80211_crypto_ops *' from 'const struct lib80211_crypto_ops *' discards qualifiers [-Werror,-Wincompatible-pointer-types-discards-qualifiers]
590 | ops = lib80211_get_crypto_ops(alg);
