clocksource/drivers/time-armada-370-xp: Fix the clock reference
While converting the init function to return an error, the wrong clock was get. This leads to the wrong clock rate and slows down the kernel. For example, it affects typical boot time: - without fix: over 1 minute - with fix: 15 seconds Tested-by: Stefan Roese <sr@denx.de> Tested-by: Ralph Sennhauser <ralph.sennhauser@gmail.com> Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Fixes: 12549e27c63c ("clocksource/drivers/time-armada-370-xp: Convert init function to return error") Link: http://lkml.kernel.org/r/1471429296-9053-1-git-send-email-daniel.lezcano@linaro.org [ Refined the changelog. ] Signed-off-by: Ingo Molnar <mingo@kernel.org>
