From: Kuan-Ying Lee <Kuan-Ying.Lee@xxxxxxxxxxxx>
[ Upstream commit 1f7a6cf6b07c74a17343c2559cd5f5018a245961 ]
MAGIC_START("IKCFG_ST") and MAGIC_END("IKCFG_ED") are moved out
from the kernel_config_data variable.
Thus, we parse kernel_config_data directly instead of considering
offset of MAGIC_START and MAGIC_END.
Fixes: 13610aa908dc ("kernel/configs: use .incbin directive to embed config_data.gz")
