Subject: [PATCH v5 1/9] Revert "media: staging/imx: add media device to capture register"
Date: Fri, 10 May 2019 14:50:04 -0700	[thread overview]
Message-ID: <20190510215012.13881-2-slongerbeam@gmail.com> (raw)
In-Reply-To: <20190510215012.13881-1-slongerbeam@gmail.com>

The imx6-specific subdevs that register a capture device will no
longer hold a reference to the media device, so this commit must be
reverted.

This reverts commit 16204b8a1c1af77725533b77936e6c73953486ae.
