Subject: [PATCH 0/6] pps: fix a UAF and clean up code

The 1st patch fixes a UAF bug. The fix is quite minimal, although a bit
ugly. The rest of the series are cleanups in the area.

Michal Schmidt (6):
  pps: fix cdev use-after-free
  pps: simplify pps_idr_lock locking
  pps: use scoped_guard for pps_idr_lock
  pps: print error in both cdev and dev error paths in
    pps_register_cdev()
  pps: embed "dev" in the pps_device
  pps: use cdev_device_add()
