mtd: nand: fixup kerneldoc, rename parameter
First, the function argument is 'offset' not 'column'. Second, the 'data_buf' name is inconsistent with the rest of this file. Just use 'buf'. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Cc: Gupta, Pekon <pekon@ti.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
