Pull EDAC fixes from Borislav Petkov:
 "Fix polling timeout setting through sysfs.

  You're surely wondering why the patches are not based on an rc.  Well,
  Andrew sent you 79040cad3f82 ("drivers/edac/edac_mc_sysfs.c: poll
  timeout cannot be zero sent you") already (it got in in -rc2) but it
  is not enough as a fix because for one, setting too low polling
  intervals (< 1sec) don't make any sense and cause unnecessary polling
  load on the system.

  Then, even if we set some interval, we explode with

    [ 4143.094342] WARNING: CPU: 1 PID: 0 at kernel/workqueue.c:1393 __queue_work+0x1d7/0x340()

  because the workqueue setup path is used also for the timeout period
  resetting and we're doing INIT_DELAYED_WORK() on an already active
  workqueue.  Which is total bollocks.  So this is taken care of by the
  second patch.

  I've CCed stable for those two"
