Atmel AIC has common structure for SMR (Source Mode Register). bit[6:5] Interrupt source type bit[2:0] Priority level Other bits are unused. To update new priority value, bit[2:0] should be cleared first and then new priority level can be written. However, aic_common_set_priority() helper clears source type bits instead of priority bits. This patch fixes wrong mask bit operation.
