From 4b5df88f1cd3cf8bbe51558fff943af9dcce00ff Mon Sep 17 00:00:00 2001 From: Klaus Kudielka Date: Sun, 28 Jul 2019 15:54:21 +0200 Subject: [PATCH] mvebu: sysupgrade: sdcard: fix platform_do_upgrade_sdcard Unconditionally execute the final case statement, even if the disk layout changed. This is necessary, to keep the original Turris Omnia flash instructions working: The disk layout WILL change, when switching from TurrisOS to OpenWRT. Without updating the uboot environment at the same time, the user would end up with an unbootable system. Fixes commit 2e5a0b81ec ("mvebu: sysupgrade: sdcard: keep user added ...")
