But introduced a new one:

drivers/net/wireless/ath/ath12k/coredump.c:1: Improper SPDX comment style for 'drivers/net/wireless/ath/ath12k/coredump.c', please use '//' instead
drivers/net/wireless/ath/ath12k/coredump.c:1: Missing or malformed SPDX-License-Identifier tag in line 1

Note that .h use /* */ and .c use // for SPDX comments

Also note that although this applies cleanly to ath-next, it does not apply cleanly to the pending branch, so it will eventually need to be rebased.
