Yes, that patch was a tremenuous failure and definitely not worth the trouble

Not sure if/how that helps. Now we have two patches with different
authors and sign-off statements, both of which need maintainer
manipulation. I'll pick the first patch into my tree and fix it up.
Let's see what Wim does with it.

I agree, due to the references to sgimc this driver will only compile for
the platforms which set SGI_HAS_INDYDOG; MIPS as the dependency is too
generic.

(MIPS && COMPILE_TEST && SGI_HAS_INDYDOG) implies SGI_HAS_INDYDOG
So I think you can just do:
- depends on SGI_HAS_INDYDOG || (MIPS && COMPILE_TEST)
+ depends on SGI_HAS_INDYDOG
I.e. COMPILE_TEST isn't of any value in this case.

[PATCH] watchdog: indydog: Add dependency on SGI_HAS_INDYDOG
Commit da2a68b3eb47 ("watchdog: Enable COMPILE_TEST where possible")
enabled building the Indy watchdog driver when COMPILE_TEST is enabled.
However, the driver makes reference to symbols that are only defined for
certain platforms are selected in the config. These platforms select
SGI_HAS_INDYDOG. Without this, link time errors result, for example
when building a MIPS allyesconfig.

indydog.c:(.text+0x54): undefined reference to `sgimc'
indydog.c:(.text+0x58): undefined reference to `sgimc'
drivers/watchdog/indydog.o: In function `indydog_stop':

drivers/watchdog/indydog.o:indydog.c:(.text+0xa8): more undefined
references to `sgimc' follow

Fix this by ensuring that CONFIG_INDIDOG can only be selected when the
necessary dependent platform symbols are built in.
