USB: revert periodic scheduling bugfix 2013-06-13T16:25:04+00:00 Alan Stern stern@rowland.harvard.edu 2013-05-28T18:03:10+00:00 9afcad40de6d98484d3d12305830656b882f76f1 commit fdc03438f53a00294ed9939eb3a1f6db6f3d8963 upstream. This patch reverts commit 3e619d04159be54b3daa0b7036b0ce9e067f4b5d (USB: EHCI: fix bug in scheduling periodic split transfers). The commit was valid -- it fixed a real bug -- but the periodic scheduler in ehci-hcd is in such bad shape (especially the part that handles split transactions) that fixing one bug is very likely to cause another to surface. That's what happened in this case; the result was choppy and noisy playback on certain 24-bit audio devices. The only real fix will be to rewrite this entire section of code. My next project...
