From 279667212ab2a4f36c3b0347657ddcc11f9cfa25 Mon Sep 17 00:00:00 2001 From: AKASHI Takahiro Date: Fri, 11 Jan 2019 16:40:21 +0900 Subject: arm64: kexec_file: return successfully even if kaslr-seed doesn't exist In kexec_file_load, kaslr-seed property of the current dtb will be deleted any way before setting a new value if possible. It doesn't matter whether it exists in the current dtb. So "ret" should be reset to 0 here.
