Hi Greg,

Actually our goal is to merge the 3 patches to 4.19.y and 4.14.y stable branch, however, I mistakenly believed that the patches should be present in 4.20.y first and did not notice that 4.20.y has been EOL. Sorry for that.

Thanks, Kaiyen

Existing data command CRC error handling on kernel 4.20 stable branch

Specifically, the assumption that the host controller will continue
operating normally after the error interrupt, is not valid. So we
suggest cherry-pick the 3 patches listed below to kernel 4.20 stable
branch, which can change the driver to handle the error in the same
manner as a data CRC error.

4bf7809: mmc: sdhci: Fix data command CRC error handling
869f8a6: mmc: sdhci: Rename SDHCI_ACMD12_ERR and SDHCI_INT_ACMD12ERR
af849c8: mmc: sdhci: Handle auto-command errors

All of the patches above have landed on kernel 5.0 stable branch.

The 4.20.y stable branch is long end-of-life, so there is nothing to be able to apply any patch to, sorry.

Remember to always check the front page of kernel.org for what trees are still active.

4.20 went EoL quite a while ago, you should be using 5.0 at this point.

I've queued these to older stable kernels, thanks.

Hi Sasha,

Actually our goal is to merge the 3 patches to 4.19.y and 4.14.y stable branch, however, I mistakenly believed that the patches should be present in 4.20.y first and did not notice that 4.20.y has been EOL. Sorry for that. Should I create another thread to issue the request for merging the 3 patches to 4.19.y and 4.14.y?

Thanks, Kaiyen
