Subject[PATCH 59/62] rndis_wlan: Use static const
Date
Using static const generally increases object text and decreases data size.
It also generally decreases overall object size.

text data bss dec hex filename
41757 2205 9896 53858 d262 drivers/net/wireless/rndis_wlan.o.old
41653 2205 9880 53738 d1ea drivers/net/wireless/rndis_wlan.o.new

Changed functions rndis_set_oid and set_bssid to take const *'s.
