Subject: [PATCH 12/13] media: i2c: Remove unused macros from ov8865
Date:   Thu, 22 Jul 2021 21:34:06 +0100
Message-Id: <20210722203407.3588046-13-djrscally@gmail.com>
In-Reply-To: <20210722203407.3588046-1-djrscally@gmail.com>

There are a number of macros defined in this driver that aren't actually
used within it. There's a lot of macros defined in total, so removing the
unused ones helps make it a bit less busy.

I wavered about including this, because it might be helpful for someone adding
support for other features in the future to have these already defined, but in
the end I thought it slightly better to be less busy.
