[PATCH] drivers: staging: wlan-ng: fix sparse warnings

[Cheng-wei Lee <lee.rhapsody@gmail.com>]

This patch fix the sparse warnings in wlan-ng/cfg80211.c
The following functions were only used in this file, so done by
declaring them into static.

drivers/staging/wlan-ng/cfg80211.c:710:6: warning: symbol
'prism2_connect_result' was not declared. Should it be static?
drivers/staging/wlan-ng/cfg80211.c:719:6: warning: symbol
'prism2_disconnected' was not declared. Should it be static?
drivers/staging/wlan-ng/cfg80211.c:725:6: warning: symbol
'prism2_roamed' was not declared. Should it be static?
