From d8c42c0c282a5edd9ea2eef4c929d9cec2798653 Mon Sep 17 00:00:00 2001 From: Juuso Oikarinen Date: Thu, 18 Feb 2010 13:25:36 +0200 Subject: wl1271: Fix PSM entry Currently the PSM entry function assumes successful operation, and enables ELP, BET and beacon filtering right away. This is bad, because the PSM entry may fail due to environmental issues, which will cause the ELP, BET and beacon filtering to be illegally enabled (because FW remains in active state.) Fix this by enabling ELP, BET and beacon filtering only after successful entry, and by ensuring the firmware is in active mode after the failure.
