[patch 2.6.28-rc5] mtd m25p80: regression fix for chip detection

[David Brownell <david-b@pacbell.net>]

From: David Brownell <dbrownell@users.sourceforge.net>

The "m25p80.c extended jedec support" patch introduced a regression
whereby every chip ended up matching the first entry in the list
of chips, since it parenthesized a test incorrectly.

This bug could cause MTD filesystem corruption, and all sorts crazy
stuff since all chips would appear to be small (128KB) Atmel chips
instead of what they really were.
