Subject: [ 110/173] pnpacpi: fix incorrect TEST_ALPHA() test

3.2-stable review patch.  If anyone has any objections, please let me know.

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

From: Alan Cox <alan@...rguk.ukuu.org.uk>

commit cdc87c5a30f407ed1ce43d8a22261116873d5ef1 upstream.

TEST_ALPHA() is broken and always returns 0.

[akpm@...ux-foundation.org: return false for '@' as well, per Bjorn]
