Hi Adrian,
With respect to the below commit, It looks like currently the retry
mechanism only handles the READ path.
I wonder could a similar retry logic feasible for the WRITE path?
Regards,

mmc_block: ensure all sectors that do not have errors are read
If a card encounters an ECC error while reading a sector it will
timeout. Instead of reporting the entire I/O request as having
an error, redo the I/O one sector at a time so that all readable
sectors are provided to the upper layers.
