The driver currently raises the following sparse warning: [...] cfg80211.c:360:42: warning: incorrect type in assignment (different base types) [...] cfg80211.c:360:42: expected unsigned int key_mgmt_suite [...] cfg80211.c:360:42: got restricted __be32 [usertype] CHECK drivers/net/wireless/microchip/wilc1000/netdev.c This conversion was needed because historically the external supplicant (observed with wpa_supplicant) expects AKM suite as big endian in NL80211_CMD_EXTERNAL_AUTH message when the AKM suite is WLAN_AKM_SUITE_SAE. This is not needed anymore: - new (to be released) versions of wpa_supplicant now reads it in host endian _while_ keeping compatibility for older drivers - for new drivers used with current/old wpa_supplicant, this conversion has been added to nl80211 to force big endian when the AKM suite is WLAN_AKM_SUITE_SAE Remove this not-needed-anymore conversion to fix the sparse warning.
