How to revert a Kernel commit?

I need to revert a Kernel commit, but I have no idea how to do so.

This is the commit: https://bugzilla.kernel.org/show_bug.cgi?id=103271#c20

I'm running Arch Linux, with linux-git (4.7).

For what I understand, I just need to edit "a/drivers/gpu/drm/radeon/si_dpm.c" and remove the following line?

Code:

{ PCI_VENDOR_ID_ATI, 0x6810, 0x174b, 0xe271, 85000, 90000 },

If so, that's what I'm doing now, I removed that line and I'm re-compiling the Kernel. However, what if that was not the case and the patch was much complex? How would I apply it?

Regards

From the patch manpage

Code:

      If you apply a patch you've already  applied,  patch  thinks  it  is  a

      reversed  patch,  and offers to un-apply the patch.  This could be con‐

      strued as a feature.

Had to tweak the PKDBUILD and Patch a bit, but it worked.

Was going to suggest you let the arch forums know about this, but I see you already have. Thanks.
