Subject: [PATCH 1/2] monitor/hmp: correctly invert password argument detection again
Date: Wed, 25 Aug 2021 11:37:00 +0200	[thread overview]
Message-ID: <20210825093701.668122-2-s.reiter@proxmox.com> (raw)
In-Reply-To: <20210825093701.668122-1-s.reiter@proxmox.com>

Commit cfb5387a1d 'hmp: remove "change vnc TARGET" command' claims to
remove the HMP "change vnc" command, but doesn't actually do that.
Instead if rewires it to use 'qmp_change_vnc_password', and in the
process inverts the argument detection - ignoring the first issue, this
inversion is wrong, as this will now ask the user for a password if one
is already provided, and simply fail if none is given.

Fixes: cfb5387a1d ("hmp: remove "change vnc TARGET" command")
