[PATCH] alpha: fix "statement with no effect" warnings
Apparently gcc 4.0 complains about "({ 0; });", which leads to -Werror breakage in one of the alpha oprofile modules. One might could argue that this is a gcc bug, in that statement-expressions should be considered to be function-like rather than statement-like for the purposes of this warning. But it's just as easy to use an inline function in the first place, side-stepping the issue. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
