# \[PATCH 3/3\] net: dsa: mt7530: add GPIOLIB dependency - From: Arnd Bergmann \ - Date: 2021-02-25 14:41:07 - List: netdev - Page: https://ratatoskr.run/netdev/2021/02/6278931 - Thread: https://ratatoskr.run/netdev/2021/02/6278929/t.md ```text From: Arnd Bergmann The new gpio support may be optional at runtime, but it requires building against gpiolib: ERROR: modpost: "gpiochip_get_data" [drivers/net/dsa/mt7530.ko] undefined! ERROR: modpost: "devm_gpiochip_add_data_with_key" [drivers/net/dsa/mt7530.ko] undefined! Add a Kconfig dependency to enforce this.
