[BLUETOOTH] net/bluetooth/hci_core.c: Use time_* macros
The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values. So following patch implements usage of the time_after() macro, defined at linux/jiffies.h, which deals with wrapping correctly Signed-off-by: S.Çağlar Onur <caglar@pardus.org.tr> Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: David S.
