From: maxime.ripard@bootlin.com (Maxime Ripard) Date: Mon, 5 Mar 2018 10:35:29 +0100 Subject: [PATCH 2/7] media: sun6i: Reduce the error level In-Reply-To: <20180305093535.11801-1-maxime.ripard@bootlin.com> References: <1519697113-32202-1-git-send-email-yong.deng@magewell.com> <20180305093535.11801-1-maxime.ripard@bootlin.com> Message-ID: <20180305093535.11801-3-maxime.ripard@bootlin.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The is_format_support function can be called in the standard format negociation path with a sensor, where it's expected to have not exactly the same set of formats available. Reduce the error logging level when we find a format not supported to not have a lot of spurious messages.
