My original patch [1] did treewide cleanups including the comedi driver. Unfortunately, commit 8ffdff6a8cfb ("staging: comedi: move out of staging directory") moved drivers/staging/comedi/ to drivers/comedi/ before my patch landed on Linus' tree from akpm tree. If Andrew Morton had used Git, 'git merge' would have resolved such file moves properly without any manual intervention. Patches in akpm tree often get broken in his quilt workflows, and then people end up with sending fixup patches.
