[PATCH] input: init struct serio_bus at compile time

[PATCH] input: init struct serio_bus at compile time

[Németh Márton]

From: Márton Németh <nm127@freemail.hu>

Initialize serio_bus structure at compile time instead of at runtime in serio_init().
This will speed up startup a little bit and also reduce code size.
