Subject: [PATCH v4 08/18] arm64: Move documentation of dcache_by_line_op
Date: Mon, 24 May 2021 09:29:51 +0100	[thread overview]
Message-ID: <20210524083001.2586635-9-tabba@google.com> (raw)
In-Reply-To: <20210524083001.2586635-1-tabba@google.com>

The comment describing the macro dcache_by_line_op is placed
right before the previous macro of the one it describes, which is
a bit confusing. Move it to the macro it describes (dcache_by_line_op).

No functional change intended.
