Subject: [PATCH v2] orinoco: release BSS structures returned by cfg80211_inform_bss()
Date: Fri, 28 Oct 2011 12:47:56 +0100	[thread overview]
Message-ID: <1319802476-4588-1-git-send-email-kilroyd@googlemail.com> (raw)
In-Reply-To: <1319796588.8931.9.camel@jlt3.sipsolutions.net>

The pointer returned by cfg80211_inform_bss is a referenced
struct. The orinoco driver does not need to keep the struct, so
we just release it.
