From dc13498ab47fdfae3cda4df712beb2e4244b3fe0 Mon Sep 17 00:00:00 2001 From: Quytelda Kahja Date: Wed, 28 Feb 2018 21:19:07 -0800 Subject: [PATCH] staging: ks7010: Use constants from ieee80211_eid instead of literal ints. Git-commit: dc13498ab47fdfae3cda4df712beb2e4244b3fe0 Patch-mainline: v4.17-rc1 References: bsc#1051510 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'.
