From 0a4ac2ea2714b5e43293f752737b8c2731a26679 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 12 May 2014 11:00:15 -0700 Subject: Input: fix ps2/serio module dependency The ps2 mouse and keyboard drivers use the "serio" framework that they correctly select in Kconfig, and that in turn depends on the i8042 driver, which is also allowed to be disabled for architectures that don't have an i8042. However, Kconfig also allows i8042 to be built as a module while the serio framework is built-in, which causes this link error: drivers/built-in.o: In function `ps2_begin_command': :(.text+0x26b6cc): undefined reference to `i8042_check_port_owner' :(.text+0x26b6d4): undefined reference to `i8042_lock_chip' drivers/built-in.o: In function `ps2_end_command': :(.text+0x26b734): undefined reference to `i8042_check_port_owner' :(.text+0x26b73c): undefined reference to `i8042_unlock_chip' On x86, a specific 'select SERIO_I8042' takes care of it, but not on the other architecture that potentially have a i8042. This patch changes the Kconfig logic to ensure that whenever there is an i8042, it does get used for the serio driver, avoiding the link error above.
