There are no mdelays larger than 10 ms in the driver. All longer
delays are done with a schedule_timeout() and they are in there either
because it would otherwise lock up on my board (at the time I tested
it and with 2 Kfir cards inserted) or because it was used in the
Windoze driver. If you change any delays please make sure that this
still works on most boards and at least mention the original value in
a comment.
