Subject: [PATCH v1 04/13] arm64: Move documentation of dcache_by_line_op
Date: Tue, 11 May 2021 15:42:43 +0100	[thread overview]
Message-ID: <20210511144252.3779113-5-tabba@google.com> (raw)
In-Reply-To: <20210511144252.3779113-1-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.
