    watchdog: indydog: Add dependency on SGI_HAS_INDYDOG · 24f8d233

    Commit da2a68b3 ("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'
    indydog.c:(.text+0x1c): undefined reference to `sgimc'
    drivers/watchdog/indydog.o: In function `indydog_start':
    indydog.c:(.text+0x54): undefined reference to `sgimc'
    indydog.c:(.text+0x58): undefined reference to `sgimc'
    drivers/watchdog/indydog.o: In function `indydog_stop':
    indydog.c:(.text+0xa4): 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.
