Date: Tue, 28 Feb 2017 22:01:20 +0100 From: Arnd Bergmann <arnd@...db.de> To: Guenter Roeck <linux@...ck-us.net> Cc: Wim Van Sebroeck <wim@...ana.be>, linux-watchdog@...r.kernel.org, Lee Jones <lee.jones@...aro.org>, linux-kernel@...r.kernel.org, Arnd Bergmann <arnd@...db.de> Subject: [PATCH 5/8] 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.
