From cfe9e88866fe892f4f71bf132c64ec8bd5256e5e Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Sun, 4 Sep 2005 01:40:20 -0500 Subject: Input: rework psmouse attributes to reduce module size Rearrange attribute code to use generic show and set handlers instead of replicating them for every attribute; switch to using attribute_group instead of creating all attributes manually. All this saves about 4K.
