Subject: [PATCH 03/16] [powerpc,iseries] Constify & voidify get_property()

From: Jeremy Kerr <[email-masked]>
Date: Wed, 12 Jul 2006 15:39:42 +1000 (EST)

Now that get_property() returns a void *, there's no need to cast its
return value. Also, treat the return value as const, so we can
constify get_property later.

iseries platform changes.

Built for iseries_defconfig
