[PATCH] net/cycx_drv: replace delay_cycx() with msleep_interruptible()
Use msleep_interruptible() instead of delay_cycx() to guarantee the task delays as expected. Remove the prototype and definition of delay_cycx(). Signed-off-by: Nishanth Aravamudan <nacc@us.ibm.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
