Copy ite_config to priv area X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=50815707eebc7ce12bfd97933a6e68a482c4d7ab;p=mv-sheeva.git [media] it913x: multiple devices on system. Copy ite_config to priv area If there are two or more different it913x devices on the system they share the same ite_config and over write its settings. To over come this, the ite_config is copied to the priv area.
