From 277d32a36cba0b42c9c6836ff07f9b978566e95c Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Sat, 23 May 2009 00:35:39 +0800 Subject: viafb: rework the I2C support in the VIA framebuffer driver This patch changes the way how the various I2C busses are used internally inside the viafb driver: Previosuly, only a single i2c_adapter was created, even though two different hardware I2C busses are accessed: A structure member in a global variable was modified to indicate the bus to be used. Now, all existing hardware busses are registered with the i2c core, and the viafb_i2c_{read,write}byte[s]() function take the adapter number as function call parameter, rather than referring to the global structure member.
