[patch 50/96] mtd_dataflash: fix probing of AT45DB321C chips.

[Greg KH]

2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Will Newton <will.newton@xxxxxxxxx>

commit 229cc58ba2b5a83b0b55764c6cb98695c106238a upstream.

Commit 771999b65f79264acde4b855e5d35696eca5e80c ("[MTD] DataFlash: bugfix,
binary page sizes now handled") broke support for probing AT45DB321C flash
chips.  These chips do not support the "page size" status bit, so if we
match the JEDEC id return early.
