[ 08/47] pnpacpi: fix incorrect TEST_ALPHA() test

[Greg Kroah-Hartman]

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

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

From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>

commit cdc87c5a30f407ed1ce43d8a22261116873d5ef1 upstream.

TEST_ALPHA() is broken and always returns 0.

[akpm@xxxxxxxxxxxxxxxxxxxx: return false for '@' as well, per Bjorn]
