I considered changing the Kconfig symbols at the time, but didn't do it because I didn't want to break existing .config files. Is that not a concern? Or do you think the long-term benefit is worth having users re-answer these config questions? We have lots of Kconfig symbols that are not what we would choose today, e.g., my misguided suggestion years ago to use "CONFIG_PCI_*" instead of "CONFIG_PCIE_*" for PCIe controller drivers that didn't have any PCIe content. If we do want this, I would think we should squash all these so we don't have breakage between this patch and the following ones. Bjorn

I added entries for the old (deprecated) symbol names that select the new ones so that should not be a problem. > If we do want this, I would think we should squash all these so we > don't have breakage between this patch and the following ones. The entries using the old names make sure that there is no breakage as long as the patches are applied in order. They also handle any new users being added to other subsystem trees. (As I mentioned in the cover letter we can drop those entries after a couple of releases.) Johan

Commits b88cbaaa6fa1 ("PCI/pwrctrl: Rename pwrctl files to pwrctrl") and 3f925cd62874 ("PCI/pwrctrl: Rename pwrctrl functions and structures") renamed the "pwrctl" framework to "pwrctrl" for consistency reasons. Rename also the Kconfig symbols so that they reflect the new name while adding entries for the deprecated ones. The old symbols can be removed once everything that depends on them has been updated. The new slot module is also renamed to reflect the framework name and match the other pwrctrl modules.
