From 96e0c6837bb2db2f00d00f5295d0e9467e24a99f Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Wed, 7 Dec 2011 21:09:03 +0200 Subject: [PATCH] wlcore/wl12xx: create per-chip-family private storage This storage is allocated in wlcore_alloc_hw and freed in free_hw. The size of the storage is determined by the low-level driver.
