For example, if the interrupt mask is set to 0x08420842, the current code will increment by that amount each iteration, leading to the following sequence of nonsense: mmc_rx_ipc_intr_mask: 969816526 mmc_rx_ipc_intr_mask: 1108361744 Change the increment to a straight assignment to make the statistics at least nominally useful.
