Subject: [PATCH] powerpc/mm: remove warning about ‘type’ being set
Date: Fri, 22 Jun 2018 21:27:47 +0200 [thread overview]
Message-ID: <20180622192749.24954-1-malat@debian.org> (raw)
‘type’ is only used when CONFIG_DEBUG_HIGHMEM is set. So add a possibly
unused tag to variable. Remove warning treated as error with W=1:
arch/powerpc/mm/highmem.c:59:6: error: variable ‘type’ set but not used [-Werror=unused-but-set-variable]
