From 413d37326700aaf708730b940b04192c36e13ef4 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 7 Feb 2017 09:59:21 -0800 Subject: Input: synaptics-rmi4 - select 'SERIO' when needed With CONFIG_SERIO=m, we get a build error for the rmi4-f03 driver, added in linux-4.10: warning: (HID_RMI) selects RMI4_F03 which has unmet direct dependencies (!UML && INPUT && RMI4_CORE && (SERIO=y || RMI4_CORE=SERIO)) drivers/input/built-in.o: In function `rmi_f03_attention': rmi_f03.c:(.text+0xcfe0): undefined reference to `serio_interrupt' rmi_f03.c:(.text+0xd055): undefined reference to `serio_interrupt' drivers/input/built-in.o: In function `rmi_f03_remove': rmi_f03.c:(.text+0xd115): undefined reference to `serio_unregister_port' drivers/input/built-in.o: In function `rmi_f03_probe': rmi_f03.c:(.text+0xd209): undefined reference to `__serio_register_port' An earlier patch tried to fix this, but missed the HID_RMI driver that does a 'select' on the F03 backend. This adds a hidden Kconfig symbol that enforces 'serio' to be enabled when RMI4-F03 is, which covers all cases.
