From 8e029eb0bcd6a7fab6dc9191152c085784c31ee6 Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Tue, 25 Feb 2020 12:28:09 -0300 Subject: [PATCH] MIPS: Fix CONFIG_MIPS_CMDLINE_DTB_EXTEND handling The CONFIG_MIPS_CMDLINE_DTB_EXTEND option is used so that the kernel arguments provided in the 'bootargs' property in devicetree are extended with the kernel arguments provided by the bootloader. The code was broken, as it didn't actually take any of the kernel arguments provided in devicetree when that option was set.
