commit 3f7f36a4559ef78a6418c5f0447fbfbdcf671956 upstream. This reverts commit 478689b5990deb626a0b3f1ebf165979914d6be4. The fix seems leading to regressions for other systems. Also, the way to check the presence of IOMMU via get_dma_ops() isn't reliable and it's no longer applicable for 6.12. After all, it's no right fix, so let's revert it at first. To be noted, the PCM buffer allocation has been changed to try the continuous pages at first since 6.12, so the problem could be already addressed without this hackish workaround.
