From 3541cd48f32233dd0c0766a3f342e3fd64b04381 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Daniel=20P=2E=20Berrang=C3=A9?= Date: Mon, 15 Apr 2019 16:45:01 +0100 Subject: usb-mtp: fix string length for filename when writing metadata MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The ObjectInfo 'length' field provides the length of the wide character string filename. This is then converted to a multi-byte character string. This may have a different byte count to the wide character string. We should use the C string length of the multi-byte string instead.
