Subject: Rivafb I2C problem, new patch


Hello,

I'm currently writing a DDC/CI tool for Linux (DDC/CI is the protocol which permits to modify monitor parameters without using the OSD), see http://www.boichat.ch/nicolas/ddcci .

I use the new rivafb I2C support, but a problem appeared: the I2C bus is immediately deleted after the DDC2 EDID is read, but I need to access it from my application!

I attached a patch which fixes this problem: the bus is deleted only when the driver is unloaded (please note that the atyfb behave like my patched version). Could you add it to the next -mm kernel release ?

I also contacted the driver maintainer but he seems not to answer (I sent an e-mail to him about a week ago).

Best regards,

Nicolas Boichat
