firewire: core: fix card->reset_jiffies overflow
On a 32-bit machine with, e.g., HZ=1000, jiffies will overflow after about 50 days, so if there are between 25 and 50 days between bus resets, the card->reset_jiffies comparisons can get wrong results. To fix this, ensure that this timestamp always uses 64 bits. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: "Stefan Richter" <stefanr@s5r6.in-berlin.de>
