From penberg@cs.helsinki.fi Wed Nov 12 13:44:33 2008 From: Pekka J Enberg Date: Thu, 30 Oct 2008 13:05:42 +0200 (EET) Subject: Staging: w35und: move source files to one directory To: Greg Kroah-Hartman Cc: Pavel Machek , linux-kernel@vger.kernel.org Message-ID: From: Pekka Enberg As we're trying to get rid of the "compatability layer" in the driver, move everything under one directory. Keeping some of the files under drivers/staging/winbond/linux is a major pain in the ass whenever you're cleaning up the driver.
