The i2c_recover_bus() returns -EOPNOTSUPP if bus recovery isn't wired up,
which the case for older Tegra SoCs at the moment. This error code is then
propagated to I2C client and might be confusing, thus return -EIO instead.

Hmm, makes sense. Maybe we should change it in the core? But with EBUSY
instead?

This also should be a good variant. I'll update the patch, thanks.
