Please use get_maintainers.pl so the right people are Cc'ed. In this case being in arch/arm64, it needs to go to Will and Catalin and lakml. They will need to apply this.
The subject and commit message needs some work. Something like:
arm64: kexec: Fix smatch 'ret' warning in load_other_segments()
Since commit ac10be5cdbfa ("arm64: Use common of_kexec_alloc_and_setup_fdt()"), smatch has a warning:
arch/arm64/kernel/machine_kexec_file.c:152 load_other_segments() warn: missing error code 'ret'
...and then the rest:
> 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. > > Signed-off-by: Lakshmi Ramasubramanian <nramas@linux.microsoft.com> > Reported-by: kernel test robot <lkp@intel.com> > Reported-by: Dan Carpenter <dan.carpenter@oracle.com>
