From f6fbeccd3e513c23de9cd8562f2b2e78d4d17912 Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Wed, 11 Jan 2012 09:42:42 +0200 Subject: [PATCH] wl12xx: cancel delayed elp work and clear flags when stopping PLT In some cases a race condition can happen if we don't cancel any pending ELP work before stopping PLT. With this commit we cancel ELP work and clear the wl->flags bitmask. Also clean up the wl elements after powering off.
