Subject: [patch] v4l: bttv driver update
Date: Tue, 7 Oct 2003 12:58:46 +0200	[thread overview]
Message-ID: <20031007105846.GA3426@bytesex.org> (raw)

  Hi,

This patch updates the bttv driver.  It depends on the videobuf patch.
Changes:

  * usual tv card list updates.
  * sysfs adaptions.
  * new, experimental i2c adapter code for bt878 chips
    (not used by default yet).
  * various minor fixes.

Please apply,

  Gerd
