From 42c84bb4603d5a375b1c8dbbbef686d24e804807 Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Thu, 30 Oct 2008 16:14:36 +0200 Subject: [PATCH] Staging: w35und: remove ->adapter from struct _HW_DATA_T Eventually we want to pass a pointer to struct ieee80211_hw around in the driver, so remove the bidirectional link between struct wb35_adapter and struct _HW_DATA_T to simplify the code.
