Old IT9135 AX needs a little bit different register settings for sleep than newer IT9135 BX. This has been broken always, as power management of the whole driver, but it started to be problem as I fixed clock. Earlier clock was disabled very first on sleep and rest of the commands were skipped by the chip as no clock, leaving tuner full power state. When I fixed clocks these PM bugs started raising out as I/O errors.
