Subject: [PATCH] usb: gadget: pch_udc: Replace cpu_to_le32() by lower_32_bits()

Git-commit: 91356fed6afd1c83bf0d3df1fc336d54e38f0458

Patch-mainline: v5.13-rc1

References: git-fixes

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]
