Most patches contain headers which include information about the author (e.g. "From: ..." or "Signed-off-by:"). We use this information to give credit to the patch authors. This patch is missing such information: https://git.busybox.net/buildroot/tree/package/readline/0000-curses-link.patch I suggest adding the information to the patch so that credit can be given appopriately.
Fixed by https://git.buildroot.net/buildroot/commit/?id=575c60ff9aaaa03662555ae9353ad4e441e7fc6f
(In reply to Fabrice Fontaine from comment #1) Shouldn't this ticket be closed as the corrected patch was merged into master?
