Subject: [PATCH] include/asm-generic/bitops.h {set,clear}_bit return void
Date: Thu, 10 Apr 2003 09:21:55 +0200 [thread overview]
Message-ID: <3E951B93.4040402@gmx.net> (raw)

Linus,
{set,clear}_bit for all arches no longer return int, but void.
This patch adjusts the generic implementation accordingly.
Regards,
Carl-Daniel
