Hi all,

After merging the rcu (I think) tree, today's linux-next build (x86_64
allnoconfig) produced this warning:

kernel/time/timer.c: In function 'schedule_timeout':
kernel/time/timer.c:969:20: warning: 'timer.expires' may be used uninitialized in this function [-Wmaybe-uninitialized]
969 | long diff = timer->expires - expires;
| ~~~~~^~~~~~~~~

Introduced by (bisected to) commit

c4127fce1d02 ("timer: Use hlist_unhashed_lockless() in timer_pending()")

x86_64-linux-gnu-gcc (Debian 9.2.1-21) 9.2.1 20191130
