This patch fixes the Problems I had with my Astrometa stick's I2C bus locking up at the end of each dvbv5-scan run until it is disconnected. There is another source of IO errors in the current driver, though. The delayed work closing the I2C gate to the tuner is often executed after rtl2832_power_ctrl has disabled the PLL. This will cause the USB transfer accessing the gate control register to fail with -EPIPE.
