Subject: [PATCH v2 06/16] arm64: Move documentation of dcache_by_line_op
Date: Mon, 17 May 2021 08:51:14 +0100	[thread overview]
Message-ID: <20210517075124.152151-7-tabba@google.com> (raw)
In-Reply-To: <20210517075124.152151-1-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.
