H A D | pps_kernel.h | diff 513b032c98b4b9414aa4e9b4a315cb1bf0380101 Sun Feb 10 03:08:32 CST 2013 George Spelvin <linux@horizon.com> pps: Add pps_lookup_dev() function
The PPS serial line discipline wants to attach a PPS device to a tty without changing the tty code to add a struct pps_device * pointer.
Since the number of PPS devices in a typical system is generally very low (n=1 is by far the most common), it's practical to search the entire list of allocated pps devices. (We capture the timestamp before the lookup, so the timing isn't affected.)
It is a bit ugly that this function, which is part of the in-kernel PPS API, has to be in pps.c as opposed to kapi,c, but that's not something that affects users.
