secs_to_jiffies() is defined in hci_event.c and cannot be reused by other call sites. Hoist it into the core code to allow conversion of the ~1150 usages of msecs_to_jiffies() that either: - use a multiplier value of 1000 or equivalently MSEC_PER_SEC, or - have timeouts that are denominated in seconds (i.e. end in 000)
This will also allow conversion of yet more sites that use (sec * HZ) directly, and improve their readability. TO: K. Y.
