Maybe "right shift too big (%u) for source type %s" (if the source type is readily available) or "right shift count (%d) >= width of type (%d)" By the way, your patch has caught something interesting in net/mac80211/tkip.c: iv32 = data[hdr_len + 4] + (data[hdr_len + 5] >> 8) + (data[hdr_len + 6] >> 16) + (data[hdr_len + 7] >> 24); Wow! -- Regards, Pavel Roskin -- To unsubscribe from this list: send the line "unsubscribe linux-sparse" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
