* tag 'pull-misc-2022-12-14' of https://repo.or.cz/qemu/armbru:
  ppc4xx_sdram: Simplify sdram_ddr_size() to return
  block/vmdk: Simplify vmdk_co_create() to return directly
  cleanup: Tweak and re-run return_directly.cocci
  io: Tidy up fat-fingered parameter name
  qapi: Use returned bool to check for failure (again)
  sockets: Use ERRP_GUARD() where obviously appropriate
  qemu-config: Use ERRP_GUARD() where obviously appropriate
  qemu-config: Make config_parse_qdict() return bool
  monitor: Use ERRP_GUARD() in monitor_init()
  monitor: Simplify monitor_fd_param()'s error handling
  error: Move ERRP_GUARD() to the beginning of the function
  error: Drop a few superfluous ERRP_GUARD()
  error: Drop some obviously superfluous error_propagate()
  Drop more useless casts from void * to pointer
