so that we don't miss events when the new count value overtakes the
previous one.

we end up being off by 1. This patch adds on the correction.

selected which supports suspend.
Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

CONFIG_PM is now set whenever we support either runtime PM in addition
to suspend and hibernate.  This causes build errors when runtime PM is
enabled on a platform, but the CPU does not have the appropriate support
for suspend.

So, switch this code to use CONFIG_PM_SLEEP rather than CONFIG_PM to
allow runtime PM to be enabled without causing build errors.
