From 42802d71dd14dd0e435a8da59d817d0c6f8a2866 Mon Sep 17 00:00:00 2001 From: "Zhu, Yi" Date: Fri, 5 Dec 2008 07:58:39 -0800 Subject: [PATCH] iwlwifi: fix "MAC in deep sleep" error This patch fixes the misue of CSR_GP_CNTRL with CSR_RESET address in polling the CSR_GP_CNTRL_REG_FLAG_MAC_CLOCK_READY bit in iwl4965_apm_reset(). This causes "MAC in deep sleep" error sometimes. The patch also fixes the timeout value and the iwl_poll_bit() return value check.
