Hi Guenter, > Should the original patch be reverted instead, and should the revert > be backported ? In other words, is this a bug fix which needs to be > applied to v6.1, or is it needed for v6.2+ only ? This isn't a regression, we're just enabling this driver on a new hardware implementation. No need to backport either. I don't think that warrants a revert, as having a separate change means we keep the rationale for both changes in the git history. Cheers, Jeremy
