Its not possible to distinguish between v3.00 and v3.01 from the SCR and that is why since commit 4324f6de6d2e ("mmc: core: enable CMD19 tuning for DDR50 mode") tuning failures are ignored in DDR50 speed mode. Cards compatible with v3.00 don't respond to CMD19 in DDR50 and this error gets printed during enumeration and also if retune is triggered at any time during operation. Update the printk level to pr_debug so that these errors don't lead to false error reports.
