SPDX identifier

Hi Kalle, Thomas,

I added SPDX tags in brcm80211 driver sources. Although it is a 
no-brainer I decided to run checkpatch for the changes and quirky stuff 
started to happen. For all files I added:

// SPDX-License-Identifier

but checkpatch started complaining I should use /* ... */ instead of //.

WARNING: Improper SPDX comment style for 
'drivers/net/wireless/broadcom/brcm80211/include/brcm_hw_ids.h', please 
use '/*' instead
#29: FILE: drivers/net/wireless/broadcom/brcm80211/include/brcm_hw_ids.h:1:
+// SPDX-License-Identifier: ISC

So I edited all patches and ran again. And again it started complaining.

WARNING: Improper SPDX comment style for 
'drivers/net/wireless/broadcom/brcm80211/brcmsmac/aiutils.c', please use 
'//' instead

So now I am in a bonkers state. It seems for header files we want /* */ 
and for c files we want //. For real?

This is on wireless-drivers-next so maybe it is already fixed, but I 
think this should be fixed.

Regards,
Arend
