this looks like a step in the right direction. But I have the feeling that it needs a lot of work before I'd consider it useful for mainline.

Thanks. Could you please also take the proc fix (6) in your upstream branch as it is clearly a bugfix (and tainting the kernel is also something that should be avoided)

Probably I should use this the next time as this series again did not cleanly apply so I just fired patch on it (which worked as it was mostly due to a slight difference in our compile fixes).
So I wanted to runtime test it as you said that it might fix the I2C/GPIO issue I debugged. I gave up for now after hitting the following errors:
drivers/video/via/via-gpio.c:74: error: field 'gpio_chip' has incomplete type
so we should either select GPIOLIB or add ifdef's to avoid the dependency?
After that I hit
drivers/video/via/via_i2c.o: In function `init_module': via_i2c.c:(.text+0x309): multiple definition of `init_module' drivers/video/via/viafbdev.o:viafbdev.c:(.init.text+0x0): first defined here drivers/video/via/via_i2c.o: In function `cleanup_module': via_i2c.c:(.text+0x10): multiple definition of `cleanup_module' drivers/video/via/viafbdev.o:viafbdev.c:(.exit.text+0x0): first defined here drivers/video/via/via-gpio.o: In function `init_module': via-gpio.c:(.text+0x1f6): multiple definition of `init_module' drivers/video/via/viafbdev.o:viafbdev.c:(.init.text+0x0): first defined here drivers/video/via/via-gpio.o: In function `cleanup_module': via-gpio.c:(.text+0x0): multiple definition of `cleanup_module' drivers/video/via/viafbdev.o:viafbdev.c:(.exit.text+0x0): first defined here
Guess that means you should only have one module init/exit per module. So either making via_i2c and via_gpio separate modules or calling these functions directly from the init/exit functions.
That's it for now as I'm really supposed to do some other stuff, too.
Thanks,
