From 0613a3b92923a08d0b0db0d4b830f71dc7325ed5 Mon Sep 17 00:00:00 2001 From: Vandana BN Date: Tue, 22 Oct 2019 04:51:40 -0300 Subject: [PATCH] media: v4l2-core: fix touch support in v4l_g_fmt [ Upstream commit 545b618cfb5cadacd00c25066b9a36540e5ca9e9 ] v4l_s_fmt, for VFL_TYPE_TOUCH, sets unneeded members of the v4l2_pix_format structure to default values.This was missing in v4l_g_fmt, which would lead to failures in v4l2-compliance tests.
