Subject: Re: BUG: SDHCI fails to DMA-unmap, and other warnings

And another one:

"mmcblk0: retrying because a re-tune was needed"

static int mmc_blk_err_check(struct mmc_card *card,
                             struct mmc_async_req *areq)
{
...
        if (brq->data.error) {
                if (need_retune && !brq->retune_retry_done) {
                        pr_info("%s: retrying because a re-tune was needed\n",
                                req->rq_disk->disk_name);
                        brq->retune_retry_done = 1;
                        return MMC_BLK_RETRY;

This looks like it'll spam the kernel log regularly if MMC/SD is used
heavily with a UHS card, which (iirc) requires regular retunes.  Why is
this message at info level, and not debug level?
