Subject: [PATCH 18/18] asm-generic: io: define relaxed accessor macros unconditionally
Date: Thu, 17 Apr 2014 14:44:21 +0100	[thread overview]
Message-ID: <1397742261-15621-19-git-send-email-will.deacon@arm.com> (raw)
In-Reply-To: <1397742261-15621-1-git-send-email-will.deacon@arm.com>

Now that no architectures using asm-generic/io.h define their own relaxed
accessors, the dummy definitions can be used unconditionally.
