Subject: [PATCH v2 07/11] media: exynos4-is: Add support for multiple sensors on one port
Date: Thu, 30 Jul 2020 16:01:10 -0700 [thread overview]
Message-ID: <BN6PR04MB0660571351D03A3A4FEDCD2CA3710@BN6PR04MB0660.namprd04.prod.outlook.com> (raw)
In-Reply-To: <20200730230114.8572-1-xc-racer2@live.ca>
On some devices, there may be multiple camera sensors attached
to the same port. Make sure we probe all of them, not just the
first one.
