Subject: [PATCH] clocksource/drivers/time-armada-370-xp: Fix the clock reference
Date: Wed, 10 Aug 2016 10:09:08 +0200	[thread overview]
Message-ID: <1470816548-8750-1-git-send-email-gregory.clement@free-electrons.com> (raw)

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.

Fixes: 12549e27c63c ("clocksource/drivers/time-armada-370-xp: Convert init function to return error")
