From 74d556bc63fbf3481100be5c8de2637972cbdaeb Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Sat, 13 Aug 2011 00:51:40 +0200 Subject: [PATCH] drivers/staging/rtl8187se: Don't pass huge struct by value struct ieee80211_network is fairly large (more than half a kilobyte), so let's pass a pointer instead of passing the entire structure by value when ieee80211_is_54g() and ieee80211_is_shortslot() need to look at a few members. Also remove parentheses around the values being returned from those two functions - 'return' is not a function.
