Moikka, thank you for the comment. (and sorry for the late reply. I was off from work until recently.)

In current DVB drivers, "struct dvb_frontend"s can be alloc'ed in two places, in FE driver itself and in the client(adapter) driver, but the patch alloc's the struct dvb_frontned in the probe() helper function, so you cannot access frontend ops before registering the driver module. The probe() helper function ref-counts the driver module as well, so from clients' point of views, the driver registering and the ref-counting are done at the same time. > > Did you make study how the others have resolved that issue?

I just read through the V4L2-core i2c subdev code and did not studied much on other modules, tbh:P Regards, akihiro -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
