Subject: watchdog: indydog: Add dependency on SGI_HAS_INDYDOG
From: Matt Redfearn <matt.redfearn@xxxxxxxx>
commit 24f8d233074badd4c18e4dafd2fb97d65838afed upstream.
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.
drivers/watchdog/indydog.o: In function `indydog_write':
indydog.c:(.text+0x18): undefined reference to `sgimc'

drivers/watchdog/indydog.o:indydog.c:(.text+0xa8): more undefined
references to `sgimc' follow
make: *** [Makefile:1005: vmlinux] Error 1
Fix this by ensuring that CONFIG_INDIDOG can only be selected when the
necessary dependent platform symbols are built in.
