Message-Id: <20180301051911.1314-1-quytelda@tamalin.org>

Subject: [PATCH 1/5] staging: ks7010: Use constants from ieee80211_eid instead of literal ints.
The case statement in get_ap_information() should not use literal integers
to parse information element IDs when these values are provided by name
in 'enum ieee80211_eid' in the header 'linux/ieee80211.h'.
