Subject: [PATCH v4 14/17] media: i2c: rdacm20: Check return values
Date: Mon, 12 Apr 2021 11:34:48 +0200	[thread overview]
Message-ID: <20210412093451.14198-15-jacopo+renesas@jmondi.org> (raw)
In-Reply-To: <20210412093451.14198-1-jacopo+renesas@jmondi.org>

The camera module initialization routine does not check the return
value of a few functions. Fix that.
