[PATCH] cfg80211: Remove unused tracepoints

[PATCH] cfg80211: Remove unused tracepoints

[Steven Rostedt]

From: Steven Rostedt <rostedt@goodmis.org>

Tracepoints that are defined take up around 5K each, even if they are not
used. If they are defined and not used, then they waste memory for unused
code. Soon unused tracepoints will cause warnings.

Remove the unused tracepoints of the cfg80211 subsystem. They are:

cfg80211_chandef_dfs_required
cfg80211_return_u32
cfg80211_return_uint
cfg80211_send_rx_auth
