From 999a4312e871d9674f2ac8734820b8a242a0783f Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 26 Jun 2019 05:48:18 -0400 Subject: [PATCH] media: v4l2-ioctl: call v4l_pix_format_touch() for TRY_FMT The function v4l_pix_format_touch() is called for S_FMT to set v4l2_pix_format fields to default values for a v4l-touch device, but it wasn't called for TRY_FMT. Add this.
