We noticed a refcounting fight between the kernel device core devm_* and the regulator core refcounting, pertaining to enable GPIOd:s that may be shared between multiple regulators.
Fix this with a series that hand it all over to the regulator core and remove any devm_* stuff pertaining to these GPIOs. This includes a patch to gpiolib to make gpiod_get_from_node() available. Just go ahead and apply this to the regulator tree. If these need to go for fixes or not is up to the regulator maintainer, but all commits have a proper Fixes: tag in case they would. I have noted in the four last commits that the gpiolib patch is a prerequisite.
