Problem Details: According to GCC, the constriction of irq_name in otx2_open() may, theoretically, be truncated. This patch takes the approach of treating such a situation as an error which it detects by making use of the return value of snprintf, which is the total number of bytes, excluding the trailing '\0', that w...
