Hello,
I just noticed the 3.4 linux kernel fails to sucessfully probe the i2c-eg20t driver. I returns with EBUSY error. It worked on the 3.0 kernel. To my view it is caused the commit 07e8a51ff68353e01d795cceafbac9f54c49132b ( i2c-eg20t: use i2c_add_numbered_adapter to get a fixed bus number). The reason it actually fails is that the i2c-isch driver is registered beforehand which gets bus number 0. But this one is the bus number the eg20t driver wants to register. A possibility is that if i2c_add_numbered_adapter failed with EBUSY just use i2c_add_adapter to get at least the driver working, but with a non-fixed bus number. Opinions?
Best regards, Alexander
