Staging: comedi: Added reading of board serial number from eeprom for m-series boards
Nothing is done with it yet, eventually it will be made available to user-space via a readable file in sysfs. From: Frank Mori Hess <fmhess@users.sourceforge.net> Cc: David Schleef <ds@schleef.org> Cc: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
