Subject: [PATCH v2] media: i2c: lm3560: use conservative defaults
Date: Mon, 16 Jul 2018 11:08:14 +0200 [thread overview]
Message-ID: <20180716090814.GA4505@amd> (raw)

If no pdata is found, we should use lowest current settings, not highest.

v2: I got notification from patchwork that patch no longer applies, so
I'm rediffing the patch.
