Kerneldoc cannot understand arrays defined like
v4l2_frame_symbol_counts.

Adding an asterisk to the name does do the trick.

Disable the kerneldoc notation for now, it is already ignored:

Wouldn't it be nicer to fix kerneldoc instead? It might not be difficult at
all.

Feel free to, but I can also give it a try.

It would be nice to have this fixed in kerneldoc itself. I'm holding this
patch back for two weeks to see if someone wants to work on kerneldoc.

If not, then I'll take this anyway to fix the noise in our build.

Note that while this header is indeed ignored in the documentation, that
is really more a bug and it would be nice to actually include this header
somewhere in our documentation. So fixing these kerneldoc warnings one way
or another is something that we should do.

Regards,

It's just waiting for Jon to apply it: (from Sakari)

Ah, that patch was CCed to me but not to linux-media, and I only searched linux-media
for it so I missed it. Good news that this is fixed in the right place.

I marked this 17/17 patch as Obsoleted in patchwork.

My bad, somehow I missed linux-media from the distribution. :-(
