Only copy the validated data into op->frames while\nholding op->bcm_tx_lock, so bcm_can_tx() and bcm_tx_timeout_handler()\ncan no longer observe a partially updated or unvalidated frame.\n\nAdd a missing error path for memcpy_from_msg() when copying CAN frame\ndata from userspace.\n\nAlso move the kt_ival1/kt_ival2/ival1/ival2 updates in bcm_tx_setup()\nunder op->bcm_tx_lock, and read kt_ival1/kt_ival2/count under the same\nlock in bcm_tx_set_expiry() and bcm_tx_timeout_handler(), closing the\ntorn 64-bit ktime_t read on 32-bit platforms.",
