sys/dev/netif/ath/ath/if_ath.c:2142]: (error) Signed integer overflow for expression 'i<<i'.

Source code is

for (i = 0; i < 32; i++)
            if (ah->ah_syncstate & (i << i))
                sc->sc_intr_stats.sync_intr[i]++;

Maybe better code

for (i = 0; i < 32; i++)
            if (ah->ah_syncstate & (1 << i))
                sc->sc_intr_stats.sync_intr[i]++;
