Subject: Re: [patch] v4l: create include/media
Date: Wed, 12 Mar 2003 16:22:41 +0100 [thread overview]
Message-ID: <20030312152241.GB13235@bytesex.org> (raw)
In-Reply-To: <20030312151934.GA13235@bytesex.org>

... and here is patch #2 which actually moves the header files
(including the fixed audiochip.h file without MIN/MAX). Must be
applied on top of the other patch.
Gerd
==============================[ cut here ]==============================
This patch creates a new include directory include/media, populates
it with a few files header files and fixups the affected drivers to
compile with the new directory layout.
The directory is intented to be used for (kernel-internal) header files
of the media drivers (which are sitting below drivers/media). For now
the video-buf.h (mm helper), tuner.h (tv/radio tuner) and audiochip.h
(tv sound decoder drivers) header files are moved. Some more header
files from the dvb folks will likely follow.
