[JFFS2] Fix dataflash support
- assume wbuf may be of size which is not power of 2 - don't make strange assumption about not padding wbuf for DataFlash - use wbuf = DataFlash page and eraseblock >= 8 Dataflash pages From: Peter Menzebach <pm-mtd@mw-itcon.de> Acked-by: Artem B. Bityutskiy <dedekind@infradead.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
