Either way ~0 will be in the correct byte order, hence
replace cpu_to_le32() by lower_32_bits(). Moreover,
it makes sparse happy, otherwise it complains:
.../pch_udc.c:1813:27: warning: incorrect type in assignment (different base types)
.../pch_udc.c:1813:27: expected unsigned int [usertype] dataptr
.../pch_udc.c:1813:27: got restricted __le32 [usertype]
