From a65ff76ac8b24df49bbf4acc38918fb52d1033b0 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Tue, 8 May 2007 00:38:20 -0700 Subject: [PATCH] rivafb/nvidiafb: Various cleanups Various cleanups to rivafb/nvidiafb's I2C code: * Drop useless par->bus. * Refactor I2C bus deletion code. * Drop useless variable initialization. * Remove unneeded include of . * Simplify +1/-1. * Add __devinit tags where possible. [adaplas] The varible initialization are not useless. However, rivafb must check if i2c bus are created properly before reading the EDID block.
