Moikka Shuah! I suspect that patch makes no sense. On DVB there is runtime PM controlled by DVB frontend. It wakes up all FE sub-devices when frontend device is opened and sleeps when closed. FE release() is not relevant at all for those sub-devices which are implemented as a proper I2C client. I2C client has own remove() for that. em28xx_dvb_init and em28xx_dvb_fini are counterparts. Those I2C drivers are load on em28xx_dvb_init so logical place for unload is em28xx_dvb_fini. Is there some real use case you need that change? regards Antti
Hi Antti, The reason I made this change is because dvb_frontend_detach() calls release interfaces for fe as well as tuner. So it made sense to move the remove after that is all done. Are you saying fe and tuner release calls aren't relevant when sub-devices implement a proper i2c client? If that is the case then, and there is no chance for these release calls to be invoked when a proper i2c is present, then my patch isn't needed. -- Shuah -- Shuah Khan Senior Linux Kernel Developer - Open Source Group Samsung Research America(Silicon Valley) shuah.kh@xxxxxxxxxxx | (970) 672-0658 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
