From 518e6540831c69422faecceee8f964bd439ac9d0 Mon Sep 17 00:00:00 2001 From: Greg KH Date: Wed, 17 Aug 2005 17:33:11 -0700 Subject: [PATCH] [PATCH] Fix manual binding infinite loop Fix for manual binding of drivers to devices. Problem is if you pass in a valid device id, but the driver refuses to bind. Infinite loop as write() tries to resubmit the data it just sent. Thanks to Michal Ostrowski for pointing the problem out.
