    V4L/DVB (4605): Fixes an issue with V4L1 and make headers-install · 8a905162
    Mauro Carvalho Chehab authored
    
    V4L1 support should be disabled when no CONFIG_VIDEO_V4L1_COMPAT is defined,
    to allow checking for broken V4L2 ports. This is very important during the
    migration phase for V4L2 API.
    However, userspace apps should be capable of using both APIs, since they need
    to test at runtime, via VIDIOCGCAP ioctl, if V4L1 is supported. So, when
    __KERNEL__ is not defined, those ioctls and corresponding structs should be
    visible.
    This patch also removes the obsolete defines HAVE_V4L1 and HAVE_V4L2, that
    where causing some confusion, and were replaced by CONFIG_VIDEO_V4L1_COMPAT
    and CONFIG_VIDEO_V4L2.

	  Support for audio/video capture and overlay devices and FM radio
	  cards. The exact capabilities of each device vary.

	  This kernel includes support for the new Video for Linux Two API,
	  (V4L2) as well as the original system. Drivers and applications
	  need to be rewritten to use V4L2, but drivers for popular cards
	  and applications for most video capture functions already exist.

	  Additional info and docs are available on the web at
	  <http://linuxtv.org>

	  Documentation for V4L2 is also available on the web at
	  <http://bytesex.org/v4l/>.

	  To compile this driver as a module, choose M here: the
	  module will be called videodev.

	  Enables a compatibility API used by most V4L2 devices to allow
	  its usage with legacy applications that supports only V4L1 api.

	  If you are unsure as to whether this is required, answer Y.

config VIDEO_V4L1_COMPAT
	bool "Enable Video For Linux API 1 compatible Layer"
	depends on VIDEO_DEV
	default y
	---help---
	  This api were developed to be used at Kernel 2.2 and 2.4, but
	  lacks support for several video standards. There are several
	  drivers at kernel that still depends on it.

	  Documentation for the original API is included in the file
	  <Documentation/video4linux/API.html>.

	  User tools for this are available from
	  <ftp://ftp.uk.linux.org/pub/linux/video4linux/>.

	  If you are unsure as to whether this is required, answer Y.
