Subject: [NET] SAA9730: Remove driver
Date: Wed, 9 Jul 2008 12:38:43 +0100 [thread overview]
Message-ID: <20080709113843.GA28319@linux-mips.org> (raw)
The only user of the board, the extremly dated and rare MIPS Atlas board,
has been removed, so this driver can go, too.
Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
---
Well, Atlas will be removed for 2.6.27 ...
