Harini Katakam 468623f696 net: macb: Add a NULL check on desc_ptp ... [ Upstream commit 85520079afce885b80647fbd0d13d8f03d057167 ] macb_ptp_desc will not return NULL under most circumstances with correct Kconfig and IP design config register. But for the sake of the extreme corner case, check for NULL when using the helper. In case of rx_tstamp, no action is necessary except to return (similar to timestamp disabled) and warn. In case of TX, return -EINVAL to let the skb be free. Perform this check before marking skb in progress.
