Subject: PATCH: powerpc: remove unused variable assignment
Date: Fri, 20 May 2011 11:13:46 +0200	[thread overview]
Message-ID: <20110520091346.GC29499@suse.de> (raw)


Hi,

gcc 4.6 with -Werror does not like setting but not using variables
anymore.

So remove it, it does not seem necessary.

Signed-off-by: Marcus Meissner <meissner@suse.de>

Ciao, Marcus
