From f429b56a7f8037ce58cf258b3bce182e376438c7 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 1 Aug 2016 04:54:24 -0300 Subject: [PATCH] [media] soc-camera/rcar-vin: remove obsolete driver MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This driver has been replaced by the non-soc-camera rcar-vin driver. The soc-camera framework is being deprecated, so drop this older rcar-vin driver in favor of the newer version that does not rely on this deprecated framework.
