From 4a029abee0f1d69cb0445657d6fa5a38597bd17d Mon Sep 17 00:00:00 2001 From: Lennart Sorensen Date: Thu, 30 Oct 2008 15:55:47 +0100 Subject: scx200_i2c: Add missing class parameter The scx200_i2c driver is missing the .class parameter, which means no i2c drivers are willing to probe for devices on the bus and attach to them.

The code below shows the same pattern, and thus should perhaps be fixed in the same way. In particular, the result of !readl(i2c->regs + S3C2410_IICCON) & S3C2410_IICCON_IRQEN is always 0.
