linux-next: build failure after merge of the kgdb tree

[Stephen Rothwell]

Hi all,

After merging the kgdb tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/tty/serial/kgdboc.c:418:13: error: expected declaration specifiers or '...' before string constant
  418 | early_param("ekgdboc", kgdboc_early_init);
      |             ^~~~~~~~~

  418 | early_param("ekgdboc", kgdboc_early_init);
      |                        ^~~~~~~~~~~~~~~~~

      |                   ^~~~~~~~~~~~~~~~~

Caused by commit

  220995622da5 ("kgdboc: Add kgdboc_earlycon to support early kgdb using boot consoles")

I have used the kgdb tree from next-20200518 for today.
