From ea9eba6a8b6b5d7a48b902d92dc2adb63b4371c0 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 21 Nov 2014 15:24:31 +0100 Subject: [PATCH] cfg80211: remove pointless channel lookup in survey code We have a channel pointer, and we use its center frequency to look up a channel pointer - which will thus be exactly the same as the original pointer. Remove that pointless lookup and just use the pointer.
