Hello,

I have a PCSpecialist notebook with SD/MMC card reader. When I insert my SD card I can browse it in Gnome, but I see the following errors in dmesg:

mmc0: SDHCI_UHS2_CAPS_PTR(65535) is wrong.
mmc0: UHS2 init fail.
mmc0: failed to initial phy for UHS-II!
mmc0: SDHCI_UHS2_CAPS_PTR(65535) is wrong.
mmc0: UHS2 init fail.

mmc0: new UHS-I speed SDR104 SDXC card at address 59b4

There are 3 patches that make all these messages debug-only.
The patches are queued for 6.17 but can be found in linux-next (1)
or mmc tree 'next' branch (2).

IIRC the card was not a UHS-II card, so initializing
UHS-I is success.  The messages may be ignored, but
will not appear from 6.17 onward.

Let me add a stable tag to those commits above. It seems really
annoying to get bugreports for something that really isn't a problem.
