[PATCH 3/28] Driver core: convert SPI code to use struct device
From: Greg KH
Date: Wed Feb 07 2007 - 19:32:23 EST
From: Greg Kroah-Hartman <gregkh@xxxxxxx>
Converts from using struct "class_device" to "struct device" making
everything show up properly in /sys/devices/ with symlinks from the
/sys/class directory.
Cc: <dbrownell@xxxxxxxxxxxxxxxxxxxxx>
