From 0d3be662ce722011f000dfd4ddee2e8f45067980 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Sat, 19 Nov 2016 22:42:50 +0100 Subject: [PATCH] firmware-utils: tplink-safeloader: keep per-device info on trailing char MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Recent refactoring introduced a regression. It ignored second argument of make_support_list function which was originally true for C2600. The new generic build_image function always passes false. This patch allows specifying trailing char in a device specific info. It also switches Archer C9 to the \0 char to make it compliant with vendor images. I verified generated images to be binary identical to the ones that were created before whole refactoring.
