32-bit CLOCK_REALTIME timestamps overflow in year 2038, so all such interfaces are deprecated now. For the FW_CDEV_IOC_GET_CYCLE_TIMER2 ioctl, we already support 64-bit timestamps, but the implementation still uses timespec.

This changes the code to use timespec64 instead with the appropriate accessor functions.

Andrew, could you pick it up in the meantime? --- drivers/firewire/core-cdev.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
