Not yet. I'll send fixes for a few of the reported drivers first, and
post v2 once some of them have been reviewed, with links to them.

I tried that, but the header (ipu6-isys.h) is in the same directory as
the .c file. With --include-headers, -I include, -I include/uapi and
-I arch/x86/include, on drivers/media/pci/intel/ipu6:

  --dir, with or without -I drivers/media/pci/intel/ipu6:  no report
  the directory's .c files named on the command line:     ipu6-isys.c:990

make coccicheck M=drivers/media/pci/intel/ipu6 loses it too. It seems to
come from --dir rather than the include path: in a copy holding the
headers and ipu6-isys.c, --dir reports line 990, but adding
ipu6-isys-csi2.c, which also includes ipu6-isys.h, loses it. Unless I
am using -I wrongly, is the header matched only for the first file that
includes it?

Yes, I'll do that in v2.

Thanks, I'll drop them.
