OK, so I did some testing on 4.9. The chip is RTS5170, btw. 0. Applied the three patches, recompiled, reloaded the module. 1. The card I originally tried is 256GB. I didn't feel like testing it thouroughly, so I just wrote a short text to the first sector, erased it once more (17 seconds again) and verified that the text is gone. 2. Erased an old 2GB SD with 160MB data on it (2.5 seconds), hexdumped the whole card, all zeros. Formatted the card, it's still alive. 3. Made a raw image of one ancient 16MB MMC, verified against image made with another reader. Erased the card (21 seconds), verified it's zeros. Restored from the image, verified restored contents with another reader. I guess it means that erasing now works and normal reading/writing remained unaffected. About the SDIO change I can only say it compiles and doesn't break the driver.
