From fd209e35b74110ee1f3371838b0782b5b02eaaba Mon Sep 17 00:00:00 2001 From: Simon Arlott Date: Thu, 10 May 2007 23:04:13 -0700 Subject: USB: cxacru: ignore error trying to start ADSL in atm_start The sysfs adsl_status attribute ignores (aside from returning -EIO to the user) any error sending a START/STOP command to the device and there is at least one firmware which never sends a response but appears to work regardless. Therefore atm_start should also continue if an error is received so that such firmware is usable. The official Conexant driver doesn't expect a reply either but this is for another device (E2 router) and a commonly used firmware does respond. Also, there is no point in changing -ECONNRESET to -ETIMEDOUT since nothing ever checks for either of these values.
