Date: Mon, 23 Oct 2006 03:22:14 +0200 From: Németh Márton <nm127@...email.hu> To: Dmitry Torokhov <dmitry.torokhov@...il.com> CC: linux-input@...ey.karlin.mff.cuni.cz, linux-kernel@...r.kernel.org Subject: [PATCH] input: init struct serio_bus at compile time From: Márton Németh <nm127@...email.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.
