linux-next: build failure after merge of the clockevents tree

[Stephen Rothwell <sfr@canb.auug.org.au>]

Hi Daniel,

After merging the clockevents tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

drivers/clocksource/versatile.c: In function 'versatile_sched_clock_init':
drivers/clocksource/versatile.c:33:11: error: 'EXNIO' undeclared (first use in this function)
   return -EXNIO;

Caused by commit

  339ecd4051c3 ("clocksource/drivers/versatile: Convert init function to return error")

I have used the clockevents tree from next-20160606 for today.
