Subject: [PATCH] drivers/watchdog/Kconfig: Update CONFIG_WATCHDOG_RTAS dependencies
Date: Fri, 26 May 2017 22:22:56 -0300	[thread overview]
Message-ID: <20170527012256.6005-1-mopsfelder@gmail.com> (raw)

drivers/watchdog/wdrtas.c uses symbols defined in arch/powerpc/kernel/rtas.c,
which are exported iff CONFIG_PPC_RTAS is selected. Building wdrtas.c without
setting CONFIG_PPC_RTAS throws the following errors:

    ERROR: ".rtas_token" [drivers/watchdog/wdrtas.ko] undefined!
    ERROR: "rtas_data_buf" [drivers/watchdog/wdrtas.ko] undefined!
    ERROR: "rtas_data_buf_lock" [drivers/watchdog/wdrtas.ko] undefined!
    ERROR: ".rtas_get_sensor" [drivers/watchdog/wdrtas.ko] undefined!
    ERROR: ".rtas_call" [drivers/watchdog/wdrtas.ko] undefined!

This was identified during a randconfig build where CONFIG_WATCHDOG_RTAS=m and
CONFIG_PPC_RTAS was not set. Logs are here:

    http://kisskb.ellerman.id.au/kisskb/buildresult/12982152/

This patch fixes the issue by selecting CONFIG_PPC_RTAS when
CONFIG_WATCHDOG_RTAS is set.
