From 3a6c4bd146cc6647daf458bbc048bd861e702f62 Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Wed, 12 Jun 2019 13:09:57 +0100 Subject: libcamera: Rename V4L2Device to V4L2VideoDevice MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In preparation of creating a new V4L2Device base class, rename V4L2Device to V4L2VideoDevice. This is a project wide rename without any intended functional change.
