From b1d7ebae09622252906f7a7da1af2e3f30f6cf0e Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Thu, 13 Feb 2014 21:19:00 +0000 Subject: [PATCH] ar71xx: fix mtdpartsize macro in image Makefile (#14961) The mtdpartsize macro triggers shell errors on various Linux distributions when the partname argument $(1) does not appear within the partmap $(2). Change the sed pattern to only emit anything if a successful substitution occured and only evaluate the arithmetic expression if something was printed by the sed program.
