From 708f48e76d6de7a90e583e2b1e6b54be1a53cc1b Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Tue, 18 Oct 2016 11:15:32 -0200 Subject: [media] v4l: Document that m2m devices have a file handle specific context Memory-to-memory V4L2 devices all have file handle specific context. Say this in the API documentation so that the user space may rely on it being the case.
