From b4125e5b1bd70d3d9c22f8926e99c87967d71734 Mon Sep 17 00:00:00 2001 From: Marco Felsch Date: Thu, 12 Mar 2020 11:31:47 +0100 Subject: [PATCH] media: tvp5150: fix set_selection rectangle handling Currently a local copy of sel->r is made and adapted to the hardware constraints. After the adaption the value is applied to the hardware but the driver forgot to reflect the adapted value to the user space. Drop the local copy and work directly on the requested rectangle instead to fix this.
