[PATCH v2 1/3] lib80211: Handle const struct lib80211_crypto_ops in lib80211
From: Christophe JAILLET <hidden>
Date: 2024-08-05 06:42:12
Also in:
kernel-janitors, linux-staging, linux-wireless, lkml
Subsystem:
802.11 (including cfg80211/nl80211), intel pro/wireless 2100, 2200bg, 2915abg network connection support, networking [general], staging subsystem, the rest · Maintainers:

lib80211_register_crypto_ops() and lib80211_unregister_crypto_ops() don't modify their "struct lib80211_crypto_ops *ops" argument. So, it can be declared as const. Doing so, some adjustments are needed to also constify some date in "struct lib80211_crypt_data", "struct lib80211_crypto_alg" and the return value of lib80211_get_crypto_ops(). Signed-off-by: Christophe JAILLET <redacted> --- Compile tested only.
