This doesn't play well with autosuspend, since we look for a valid status reply to make sure the device is still present when it resumes. Without both bytes, we assume the device has been disconnected. Lack of the second byte shouldn't matter much, since the spec requires it always to be equal to 0. Hence this patch (as959) causes finish_port_resume() to accept a 1-byte reply as valid. Signed-off-by: Alan Stern Acked-by: David Brownell Signed-off-by: Greg Kroah-Hartman +LA’
