Subject: spapr.c: add 'unplug already in progress' message for PHB unplug
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7420033ec460e7b9906bf05fbe1a0d3830536657;p=qemu.git

spapr.c: add 'unplug already in progress' message for PHB unplug

Both CPU hotunplug and PC_DIMM unplug reports an user warning,
mentioning that the hotunplug is in progress, if consecutive
'device_del' are issued in quick succession.

Do the same for PHBs in spapr_phb_unplug_request().
