From 52b855600c5c16c13b6f288f3536d01c2603e78d Mon Sep 17 00:00:00 2001 From: Dongxiao Xu Date: Sun, 31 May 2009 14:43:51 +0800 Subject: [PATCH] Staging: heci: fix typos and add wait after disconnect - Fix typo for enum HECI_WRITE. - Fix timeout issue. If the time period is greater or equal 15s, it's timeout. - Add 10ms wait time after disconnect, to ensure that hardware is ready. Otherwise in the next time connection, hardware resource may be busy.
