Yes, I know. As I wrote in one of the previous patches when reviewing it, I disabled GPIO CD and used the internal mechanism (for tests where it is relevant). Like here, too. > - GPIO is not set up -> mmc_gpio_get_cd() returns -ENOSYS Thanks! That pointed me to the right direction. I missed that patch 10/22 was still under discussion and not applied to mmc/next, so I had to pick it manually. I can confirm now that there is an issue and your patch fixes it for the non-GPIO case. For the GPIO case, however, the TMIO_STAT_CARD_REMOVE | TMIO_STAT_CARD_INSERT interrupts are enabled now, too. It didn't harm when doing my tests, but we shouldn't do it, to be safe IMO.
