From 3efdf62c5f68007020ef935ad2887e7fc4e31c36 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 7 May 2015 22:12:32 -0300 Subject: [media] media: use macros to check for V4L2 subdev entities Instead of relying on media subtype, use the new macros to detect if an entity is a subdev or an A/V DMA entity. Please note that most drivers assume that there's just AV_DMA or V4L2 subdevs. This is not true anymore, as we've added MC support for DVB, and there are plans to add support for ALSA and FB/DRM too. Ok, on the current pipelines supported by those drivers, just V4L stuff are there, but, assuming that some day a pipeline that also works with other subsystems will ever added, it is better to add explicit checks for the AV_DMA stuff.
