The feature-fixup test declare some extern void variables and then take their addresses. Fix this by declaring them as extern u8 instead. Fixes these warnings (treated as errors): CC arch/powerpc/lib/feature-fixups.o cc1: warnings being treated as errors arch/powerpc/lib/feature-fixups.c: In function 'test_cpu_macros': arch/powerpc/lib/feature-fixups.c:293:23: error: taking address of expression of type 'void' arch/powerpc/lib/feature-fixups.c:294:9: error: taking address of expression of type 'void' arch/powerpc/lib/feature-fixups.c:297:2: error: taking address of expression of type 'void' arch/powerpc/lib/feature-fixups.c:297:2: error: taking address of expression of type 'void' arch/powerpc/lib/feature-fixups.c: In function 'test_fw_macros': arch/powerpc/lib/feature-fixups.c:306:23: error: taking address of expression of type 'void' arch/powerpc/lib/feature-fixups.c:307:9: error: taking address of expression of type 'void' arch/powerpc/lib/feature-fixups.c:310:2: error: taking address of expression of type 'void' arch/powerpc/lib/feature-fixups.c:310:2: error: taking address of expression of type 'void' arch/powerpc/lib/feature-fixups.c: In function 'test_lwsync_macros': arch/powerpc/lib/feature-fixups.c:321:23: error: taking address of expression of type 'void' arch/powerpc/lib/feature-fixups.c:322:9: error: taking address of expression of type 'void' arch/powerpc/lib/feature-fixups.c:326:3: error: taking address of expression of type 'void' arch/powerpc/lib/feature-fixups.c:326:3: error: taking address of expression of type 'void' arch/powerpc/lib/feature-fixups.c:329:3: error: taking address of expression of type 'void' arch/powerpc/lib/feature-fixups.c:329:3: error: taking address of expression of type 'void' Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
