Well, you should have put subject to that sentence, so that we can understand. And not to parse "Has" as a tool/person name ;).

drivers/leds/trigger/ledtrig-tty.c:362:3: error: a label can only be
part of a statement and a declaration is not a statement

Hence move the variable definition to the beginning of the function.

Is this kernel test robot broken?

The test robot does nothing wrong.

I see no label definition here.

case is a label.

And this variable declaration is at the start of a new block which does not
even require C99 support.

Nah. The block begins after the switch.
So
"""
switch (X) {
type var;
case X:
}
would work. Moving the def after case is no longer at the block beginning.

So just wrap put the case code in a block like we are used to:
"""
case X: {
  type var;
}
""".
