Subject: [PATCH v2] media: ov7740: use SCCB regmap
Date: Thu, 6 Aug 2020 21:18:27 +0530 [thread overview]
Message-ID: <1596728907-32120-1-git-send-email-raagjadav@gmail.com> (raw)
Make use of SCCB APIs for regmap operations.
Remove i2c_check_functionality as devm_regmap_init_sccb
does it for us.
Signed-off-by: Raag Jadav <raagjadav@gmail.com>
