As Thomas suggested, timespec64_valid()\nonly check the timespec is valid, but not ensure that the time is\nin a valid range, so check it ahead using timespec64_valid_strict()\nin pc_clock_settime() and return -EINVAL if not valid.\n\nThere are some drivers that use tp->tv_sec and tp->tv_nsec directly to\nwrite registers without validity checks and assume that the higher layer\nhas checked it, which is dangerous and will benefit from this, such as\nhclge_ptp_settime(), igb_ptp_settime_i210(), _rcar_gen4_ptp_settime(),\nand some drivers can remove the checks of
