This unbreaks dfu mmc_file_op which is currently broken since using the load cmd on a buffer from heap is not allowed - added with commitaa3c609e2b("fs: prevent overwriting reserved memory") Fixes: commitaa3c609e2b("fs: prevent overwriting reserved memory") Reported-by: Stephen Warren <swarren@wwwdotorg.org> Signed-off-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com> Tested-by: Stephen Warren <swarren@nvidia.com> Acked-by: Lukasz Majewski <lukma@denx.de>
