[PATCH v3 0/7] ASoC: topology: Change to resource managed memory
Almost all other allocations in ASoC API are resource managed, the only exception is soc-topology.c.
This patchset clean ups few unnecessary functions in preparation for change and then changes to devm_ functions for allocation.

Eh... and of course I've messed up something, there shouldn't be v3 in the topic of cover letter ;) I can resend if you want?

These address some of the long standing issues of resource allocation for topology, thanks for your work. Nitpick: *the 0/7* looks weird given that only 6 patches are actually part of the series.
For the series:

Yes that was a copy&paste mistake, similarly to already mentioned v3. There is only 6 patches.
It is a problem caused by manually filling cover letter and copying title from old cover letter to new one.
I did some reading, and apparently if one operates on branches to prepare patch sets, they can do something like: $ git branch --edit-description $ git format-patch -6 --cover-letter --cover-from-description=subject And git will automatically populate cover letter with text from branch description. I will try to remember to try it when sending another series. Hopefully this will allow me to avoid copy&paste mistakes, as filling cover letter title and description will be automated ;)
Mark, do let me know if you want me to resend.

Topology API exposes snd_soc_tplg_widget_remove and snd_soc_tplg_widget_remove_all, but both are nowhere used. All current users load and unload topology as a whole. As following commits introduce resource managed memory, remove them to simplify code and reduce maintenance burden.

In theory topology can be loaded in multiple steps by providing index to snd_soc_tplg_component_load, however, from usability point of view it doesn't make sense, as can be seen from all current users loading topology in one go. Remove the unnecessary parameter.

In few places tplg->comp->dev is used, while everywhere else tplg->dev is being used. Unify those uses towards tplg->dev, as it is being set to comp->dev during initialization anyway.

In order for topology to be resource managed, change all allocations to be resource managed: k*alloc -> devm_k*alloc kstrdup -> devm_kstrdup
Exceptions where non resource managed allocation is left is soc_tplg_dapm_widget_create(), as it uses pointer to memory locally and frees it up after use, as well as soc_tplg_dapm_graph_elems_load(), which has temporary pointer to table of routes.
After conversion all redundant calls in error and clean up paths were removed.
Also removed some variables which become unneeded when there is no calls using them.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
