Subject: vnc: Clean up error reporting in vnc_init_func()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=612aea201738cd747b02d2c2acd6e0bf406531cf;p=qemu.git

vnc: Clean up error reporting in vnc_init_func()

Calling error_report() in a function that takes an Error ** argument
is suspicious.  vnc_init_func() does that, and then fails without
setting an error.  Its caller main(), via qemu_opts_foreach(), is fine
with it, but clean it up anyway.

While there, drop a "Failed to start VNC server: " error message
prefix that doesn't really add value.
