From: Zhu, Yi <yi.zhu@xxxxxxxxx> 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.
