From 42d74e4fe6508308abc1baac95ba36ad0cc5143e Mon Sep 17 00:00:00 2001 From: Nobuhiro Iwamatsu Date: Tue, 13 Jan 2015 21:55:02 -0300 Subject: [PATCH] [media] rcar_vin: Update device_caps and capabilities in querycap The V4L2 API requires both .capabilities and .device_caps fields of struct v4l2_capability to be set. Otherwise the compliance checker complains and since commit "v4l2-ioctl: WARN_ON if querycap didn't fill device_caps" a compile-time warning is issued. Fix this non-compliance in the rcar_vin driver.
