I can propose the following plan of action for such a rename: 1. Temporarily have both UCMs 2. Wait until distros update their packages 3. Change the name in kernel without extra config options 4. Remove the now deprecated UCMs ...that's requiring a bit of time, yes, but I think this is the best way to ensure that no breakage happens in the meantime for any users. Anyone disagreeing? Does anyone have any better idea?

Wait until distros update their packages It's not possible to monitor the package version for every single distro, so I guess you mean tracking only the big distros and hoping that no small distro still uses the old version. Also, is UCM the only userspace tool that might use this name? There might be others too that we would need to care about. > 3. Change the name in kernel without extra config options > 4.

My worry is that we don't know how long it would take, if a small distro decides to keep using the old version. But even in the best case it might take years for the old version to be phased out, I'm not sure I'll be around for that, so maybe we'll just keep using the old name forever. The nice thing about the config is that distros and users can opt-in immediately to get rid of the error. For example KernelCI, which is monitoring such errors, can enable this config to fix this error right now. Thanks, Nícolas

Commit c8d18e440225 ("ASoC: core: clarify the driver name initialization") introduced an error message when driver names are automatically generated and result in truncated names. For example, this error message is printed on mt8195-cherry-tomato-rev2: mt8195_mt6359 mt8195-sound: ASoC: driver name too long 'sof-mt8195_r1019_5682' -> 'sof-mt8195_r101' Since that truncated driver name is already used by userspace (eg UCM), it can't be unconditionally updated. As suggested by Jaroslav, update the driver name but hide it behind a kernel config option, which Linux distributions can enable once the corresponding support in userspace audio configuration software lands. This ensures that audio doesn't regress, while still allowing the error to be fixed.
