commit 8396c793ffdf28bb8aee7cfe0891080f8cab7890
Author: Sam Protsenko <semen.protsenko@xxxxxxxxxx>
Date: Wed Mar 6 17:20:52 2024 -0600
mmc: dw_mmc: Fix IDMAC operation with pages bigger than 4K
that the problem does appear to have resolved itself, I tested this on
a variety of devices.
Best regards,
Adam
