This makes static checker unhappy:

/home/cocci/testing/include/net/psp/types.h:167:6-18: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-a...)

I think/guess the warning could be avoided using something alike the following (completely untested!!!):

It's not a VLA, it's an end marker for calculating offsets. The patch is fine, we should have added in the commit msg that the false positive from cocci is expected.

I guess we could avoid this problem by naming the union. Let's do that instead..
