The double word returned by read_afu_info(OCXL_DVSEC_TEMPL_NAME) contains four characters of the AFU name, read from the PCI config space, hence with a little-endian ordering. When composing the string, a big-endian system must swap the bytes so that the characters appear in the right order. Do this with le32_to_cpu(). Signed-off-by: Greg Kurz <groug@xxxxxxxx> ---
