powerpc: Free fdt on error in elf64_load()
There are a few "goto out;" statements before the local variable "fdt" is initialized through the call to of_kexec_alloc_and_setup_fdt() in elf64_load(). This will result in an uninitialized "fdt" being passed to kvfree() in this function if there is an error before the call to of_kexec_alloc_and_setup_fdt(). If there is any error after fdt is allocated, but before it is saved in the arch specific kimage struct, free the fdt. Fixes: 3c985d31ad66 ("powerpc: Use common of_kexec_alloc_and_setup_fdt()") Reported-by: kernel test robot <lkp@intel.com> Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Lakshmi Ramasubramanian <nramas@linux.microsoft.com> Signed-off-by: Rob Herring <robh@kernel.org> Link: https://lore.kernel.org/r/20210421163610.23775-1-nramas@linux.microsoft.com
