From 946eba9a92ab42aa0a32d5bba51f76dd53ca5fcf Mon Sep 17 00:00:00 2001 From: Tokunori Ikegami Date: Sun, 5 Jan 2020 17:13:03 +0900 Subject: [PATCH] ath79: Remove mtd cfi_cmdset_0002 status check patches Currently the patch only changes break to use goto statement instead. But not necessary acutually since the ret value checked after the for loop. So it is okay for the break case before changed by the patch also. This patch only reverts the following commit partially. https://github.com/openwrt/openwrt/commit/ddc11c3932c7b7b7df7d5fbd48f207e7 Note: The changes are mainly applied into the linux kernel upstream.
