Subject: [PATCH 4.4 019/132] platform/x86: asus-wmi: add SERIO_I8042 dependency

From: Arnd Bergmann <arnd@...db.de>

[ Upstream commit ea893695ec1131a5fed0523ff8094bc6e8723bbe ]

A recent bugfix added a call to i8042_install_filter but did
not add the dependency, leading to possible link errors:

drivers/platform/built-in.o: In function `asus_nb_wmi_quirks':
asus-nb-wmi.c:(.text+0x23af): undefined reference to `i8042_install_filter'

This adds a dependency on SERIO_I8042||SERIO_I8042=n to indicate
that we can build the driver when the i8042 driver is disabled,
but it cannot be built-in when that is a loadable module.
