Subject: [PATCH v2 06/11] media: exynos4-is: Use global num_sensors rather than local index
Date: Thu, 30 Jul 2020 16:01:09 -0700	[thread overview]
Message-ID: <BN6PR04MB066025E2D254EF0E5383B7FCA3710@BN6PR04MB0660.namprd04.prod.outlook.com> (raw)
In-Reply-To: <20200730230114.8572-1-xc-racer2@live.ca>

Instead of keeping a local copy of how many sensors we've probed
(which may not even properly represent the number of sensors
probed if we have a port without a sensor), use the global
num_sensors counter that has the actual number used.

This will also make it easier to add support for multiple sensors
being connected to the same port.
