[Qemu-block] [PATCH 0/2] block: add blk_lookup() for getting device by node_name

[Anton Kuchin]

Some HMP and QMP commands are targeting BlockBackend but
for hotplugged devices name of BB is deprecated, instead
name of root BlockDriverState is set. These patches add
functions to search BB by attached root BDS name.

This approach isn't perfect, but I couldn't invent a better
one and I belive it's more convinient than accessing BB
by QOM path.

  block: add functions to search BlockBackend by root BDS name
  block: migrate callers from blk_by_name to blk_lookup
