v2->v3:

Changes suggested by Peter Maydell:
  timer_free() already contains timer_del()(commit 5f8e93c3e262ab),
so delete unnecessary timer_del() function.


v1->v2:

patch1:
  Delete the modification of unrelated whitespace.
patch2:
  Add David Gibson acked tag.
patch3:
  Has been applied, so delete it.


Gan Qixin (2):
  pl031: Use timer_free() in the finalize function to avoid memleaks
  misc/mos6522: Use timer_free() in the finalize function to avoid
    memleak

When running device-introspect-test, a memory leak occurred in the pl031_init
function, this patch use timer_free() in the finalize function to fix it.

ASAN shows memory leak stack:

When running device-introspect-test, a memory leak occurred in the mos6522_init
function, this patch use timer_free() in the finalize function to fix it.

As the change from v2 -> v3 is a rebase suggested by
Peter, you can keep David's tag IMO:
