PCH_UDC_DMA_LAST is 0x08000000 so a bit-or with this value always gives a
nonzero result. The test is rewritten as done elsewhere in the same file.
This problem was found using Coccinelle (http://coccinelle.lip6.fr/).

But why not simply:
if (td_data->status & PCH_UDC_DMA_LAST)
if the constant is single bit anyway? And are you sure about s/td/td_data/?
