mtd: nand: pxa3xx: Add a nice comment to pxa3xx_set_datasize()
Add a comment clarifying the use of pxa3xx_set_datasize() which is only applicable on data read/write commands (i.e. commands with a data cycle, such as READID, READ0, STATUS, etc.) Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
