Subject: misc: ioc4: Use ktime_get_ns()
X-Git-Tag: MMI-PSA29.97-13-9~11784^2~32
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6d9b757c6ce850d0fb61d31f48e7bae56240643b;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

misc: ioc4: Use ktime_get_ns()

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