From e399d779c9acf277488c5b306b71dcbc71e160ca Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 8 Aug 2025 17:17:57 +0200 Subject: mfd: si476x: Add GPIOLIB_LEGACY dependency This driver uses the legacy gpiolib interfaces to get gpio numbers from platform data: drivers/mfd/si476x-i2c.c: In function 'si476x_core_start': drivers/mfd/si476x-i2c.c:133:21: error: implicit declaration of function 'gpio_is_valid'; did you mean 'uuid_is_valid'? [-Werror=implicit-function-declaration] 133 | if (gpio_is_valid(core->gpio_reset)) There are no in-tree users of this driver, so nothing defines the platform data. Add a dependency on GPIOLIB_LEGACY for the moment to avoid the build failure, and make sure the sound driver does not get built without the mfd portion either pass that dependency along. Alternatively, we could remove the mfd driver along with the radio and sound portions.
