From d203e59c4b56d56916a804ebeb04b0e6d92adf4c Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Wed, 30 Nov 2011 12:30:01 +0200 Subject: [PATCH] wlcore/wl12xx: add quirk for legacy NVS support Instead of checking the chip ID directly in the wlcore code to decide whether to use the new or the old NVS format, we now use a quirk that should be set by the low level driver to say that it needs to use the old format.
