firewire: ohci: do not start DMA contexts before link is enabled OHCI 1.1 5.7.3 not only forbids enabling or starting any DMA contexts before the linkEnable bit is set, but also explicitly warns of undefined behaviour if this order is violated. Don't violate it then. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
