OK, in an honest attempt to at least remove as many of the checkpatch
errors as I can, I am running into the paradoxical situation where I
either get

ERROR: space required after that ',' (ctx:VxO)
#83: FILE: include/linux/init.h:232:
+#define console_initcall(fn) ___define_initcall(fn,, .con_initcall)

or

ERROR: space prohibited before that ',' (ctx:WxW)
#156: FILE: include/linux/init.h:232:
+#define console_initcall(fn) ___define_initcall(fn, , .con_initcall)
^
which I think may be checkpatch trying to give me a hint that I have
done enough work for the week, and should spend some time by the pool
instead.
