Subject: init/main.c: use ktime accessor function in initcall_debug code
X-Git-Tag: firefly_0821_release~13991^2~453^2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1d926f2756392c6909f60e0c9fe2a09d5462e376;p=firefly-linux-kernel-4.4.55.git

init/main.c: use ktime accessor function in initcall_debug code

Impact: fix initcall debug output on non-scalar ktime platforms (32-bit embedded)

The initcall_debug code access the tv64 member of ktime.  This won't work
correctly for large deltas on platforms that don't use the scalar ktime
implementation.
