Hi all,

This small series contains a few fixes for the hrtimer code in RT linux
(v5.2.9-rt3-rebase).

The patch #2 contains a error I managed to reproduce. The other two are
were found while looking at the code.

Cheers,

Julien Grall (3):
  hrtimer: Use READ_ONCE to access timer->base in
    hrimer_grab_expiry_lock()
  hrtimer: Don't grab the expiry lock for non-soft hrtimer
  hrtimer: Prevent using uninitialized spin_lock in
    hrtimer_grab_expiry_lock()
