The header doesn't match the existing license.

Furthermore, unless I'm mistaken, the standard comment style for SPDX headers 
in the kernel is //, not /* ... */

When I added the file, I must have cut and pasted the license statement
from another file. More on this below the deleted license lines.

Looks like we have 3 conventions for SPDX comment style.
/* ... */ for headers and # ... for shell scripts and
// for .c files.

I can update it it and send v2 provided we think the change is inline
with the original license.

Are you concerned about the "or (at your option) any later version." part
that it doesn't match?

Personally I prefer the /* ... */ comment style, but I noticed that Greg used 
// in his large patch the adds SPDX license headers, so I think we should 
follow the established practice. I'll let you investigate to find what is 
preferred :)

Yes, that's my concern. I'm personally fine with GPL-2.0-only, but you'll have 
a hard time contacting all the other copyright holders if you want to 
relicense this. Good luck getting hold of the appropriate legal department at 
Nokia :-)

On a related note, I nowadays encourage developers to keep their copyright on 
code they wrote when possible, and to at least negotiate that with their 
employers.

Yeah /*...*/ is my preferred as well. Hence  the autopilot change I made
in the first place. I redid a couple of patches already to follow the
// convention and I can do the same here.

Yeah. I don't think it is beneficial to continue this effort. I am going to not
pursue the patch at this file. Thanks for the review.

How about just using

// SPDX-License-Identifier: GPL-2.0-or-later

? That is equivalent to the current license text.

Hmm. Yes GPL-2.0-or-later would maintain the intent and doesn't change
the license. I can send v2 with that and see anybody objects to it.
