Messages in this thread Patch in this message | | | From | Lakshmi Ramasubramanian <> | Subject | [PATCH] [kexec]: arch/arm64/kernel/machine_kexec_file.c:152 load_other_segments() warn: missing error code 'ret' | Date | Wed, 8 Dec 2021 09:09:10 -0800 |
| |
Return code is not set to an error code in load_other_segments() when of_kexec_alloc_and_setup_fdt() call returns a NULL dtb. This results in status success (return code set to 0) being returned from load_other_segments().
Set return code to -ENOMEM if of_kexec_alloc_and_setup_fdt() returns NULL dtb.
