Subject: [patch 36/55] misc: ioc4: Use ktime_get_ns()
Date: Fri, 11 Jul 2014 13:44:52 -0000	[thread overview]
Message-ID: <20140711133708.353543709@linutronix.de> (raw)
In-Reply-To: 20140711133623.530368377@linutronix.de

[-- Attachment #1: misc-ioc4-remove-silly-time-stamp-dance.patch --]
[-- Type: text/plain, Size: 1505 bytes --]

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