[patch 34/55] connector: Use ktime_get_ns()

[Thomas Gleixner <tglx@linutronix.de>]

[-- Attachment #1: connector-remove-silly-timestamp-dance.patch --]
[-- Type: text/plain, Size: 6565 bytes --]

Replace the ever recurring:
        ts = ktime_get_ts();
        ns = timespec_to_ns(&ts);
with
        ns = ktime_get_ns();
