watchdog: menf21bmc: add I2C dependency
This driver fails to link when CONFIG_I2C is disabled or a loadable module while the watchdog is built-in: drivers/watchdog/built-in.o: In function `menf21bmc_wdt_shutdown': menf21bmc_wdt.c:(.text+0x9b44): undefined reference to `i2c_smbus_write_word_data' menf21bmc_wdt.c:(.text+0x9b44): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `i2c_smbus_write_word_data' This adds a Kconfig dependency for it, to enforce a valid configuration. Fixes: da2a68b3eb47 ("watchdog: Enable COMPILE_TEST where possible") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
