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. Signed-off-by: Dongxiao Xu <dongxiao.xu@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
