Subject: spice-chardev: listen to frontend guest open / close
X-Git-Tag: v0.15.0-rc0~330^2~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=cd8f7df2891891c3a6c346892545c4407be6699f;p=thirdparty%2Fqemu.git

spice-chardev: listen to frontend guest open / close

Note the vmc_register_interface() in spice_chr_write is left in place
in case someone uses spice-chardev with a frontend which does not have
guest open / close notification.
