From 67873d4e751e400149df7ab61ba04cbb4cc0d449 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 11 Feb 2016 15:35:07 -0200 Subject: [PATCH] [media] use v4l2_mc_usb_media_device_init() on most USB devices Except for the usbuvc driver (with has an embedded media_device struct on it), the other drivers have a pointer to media_device. On those drivers, replace their own implementation for the core one. That warrants that those subdev drivers will fill the media_device info the same way.
