From 87c7fb7819962e052a69046167949fe266611abf Mon Sep 17 00:00:00 2001 From: Leo Yan Date: Thu, 4 Jan 2024 21:09:44 +0000 Subject: hw/virtio: Move vhost-user-input into virtio folder MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit vhost-user-input is in the input folder. On the other hand, the folder 'hw/virtio' maintains other virtio stubs (e.g. I2C, RNG, GPIO, etc). This patch moves vhost-user-input into the virtio folder for better code organization. No functionality change.
