Oh and this appears in the logs when I remove the card:
[11721.313471] rtsx_sdmmc: Realtek SDMMC controller has been removed
but it is simply polluting the logs with useless info that a card has
been removed.
If you really need those printk (same with the PCI-E driver) you could
try to use dev_dbg() like you do above.
Same for the probe function.
But, more importantly and while playing with this, I replugged the card
and it said:
[12072.632332] rtsx_core: MMC/SD card detected in socket 0:0
[12072.642855] rtsx_sdmmc: Realtek SDMMC controller found
[12073.839561] mmc0: error -110 whilst initialising SD card
[12075.138833] mmc0: error -110 whilst initialising SD card
[12076.438158] mmc0: error -110 whilst initialising SD card
and now I can't mount the card anymore:
$ mount /dev/mmcblk0 /mnt/tmp/
mount: /dev/mmcblk0 is not a valid block device
$ mount /dev/mmcblk0p1 /mnt/tmp/
mount: /dev/mmcblk0p1 is not a valid block device
Hmm..
