Subject[PATCH 1/3] clocksource/drivers/time-armada-370-xp: Fix the clock reference
Date
From: Gregory CLEMENT <gregory.clement@free-electrons.com>

While converting the init function to return an error, the wrong clock
was get. This lead to wrong clock rate and slow down the kernel. For
example, before the patch a typical boot was around 15s after it was 1
minute slower.
