From f2e9084779d3ad3b51ee45a3a53fead3f16516ca Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 29 Jan 2014 10:07:13 -0300 Subject: [media] v4l: Validate fields in the core code for subdev EDID ioctls The subdev EDID ioctls receive a pad field that must reference an existing pad and an EDID field that must point to a buffer. Validate both fields in the core code instead of duplicating validation in all drivers.
