Herve Codina 3dc0ec46f6 i2c: muxes: i2c-mux-gpmux: Use of_get_i2c_adapter_by_node() ... i2c-mux-gpmux uses the pair of_find_i2c_adapter_by_node() / i2c_put_adapter(). These pair alone is not correct to properly lock the I2C parent adapter. Indeed, i2c_put_adapter() decrements the module refcount while of_find_i2c_adapter_by_node() does not increment it. This leads to an underflow of the parent module refcount. Use the dedicated function, of_get_i2c_adapter_by_node(), to handle correctly the module refcount.
