[PATCH 00/15] spapr: Error handling fixes and cleanups (round 2)

[Greg Kurz]

Yet another round of sanitizing the error handling in spapr. I've
identified locations that needed fixing with the errp-guard.cocci
coccinelle script. It turns out that a better result is achieved
by fixing manually, especially by converting some void functions
to indicate success/failure with a return value.

Greg Kurz (15):
  spapr: Fix error leak in spapr_realize_vcpu()
  ppc: Add a return value to ppc_set_compat() and ppc_set_compat_all()
  ppc: Fix return value in cpu_post_load() error path
  spapr: Simplify error handling in callers of ppc_set_compat()
  spapr: Get rid of cas_check_pvr() error reporting
  spapr: Simplify error handling in do_client_architecture_support()
  spapr: Simplify error handling in spapr_vio_busdev_realize()
  spapr: Add a return value to spapr_drc_attach()
  spapr: Simplify error handling in prop_get_fdt()
  spapr: Add a return value to spapr_set_vcpu_id()
  spapr: Simplify error handling in spapr_cpu_core_realize()
  spapr: Add a return value to spapr_nvdimm_validate()
  spapr: Add a return value to spapr_check_pagesize()
  spapr: Simplify error handling in spapr_memory_plug()
  spapr: Simplify error handling in spapr_memory_unplug_request()
