Clang warns: drivers/infiniband/hw/hfi1/msix.c:136:22: warning: overlapping comparisons always evaluate to false [-Wtautological-overlap-compare] if (type < IRQ_SDMA && type >= IRQ_OTHER) ~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~ 1 warning generated. It is impossible for something to be less than 0 (IRQ_SDMA) and greater than or equal to 3 (IRQ_OTHER) at the same time. A logical OR should have been used to keep the same logic as before.
