[ Upstream commit 91356fed6afd1c83bf0d3df1fc336d54e38f0458 ]
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]
