From a07e47a47f57646d9b18aebd47dbfee667e19986 Mon Sep 17 00:00:00 2001 From: Thomas De Schampheleire Date: Tue, 7 Feb 2017 22:56:38 +0100 Subject: [PATCH] toolchain-external: reduce nesting in copy_toolchain_sysroot As discussed with Thomas Petazzoni, we can reduce the nesting level by early returning on an invalid iteration. I did not move the 'else' case (the common case) outside the if-else because it would make the code less symmetrical and IMO makes it _less_ clear.
