That commit triggered a new WARN when unloading the module (see at the end of the commit message). When a class_dev is embedded in a structure then that class_dev is the thing that controls the lifetime of that structure, for that reason device managed allocations can't be used here. See Documentation/kobject.txt. Revert the above patch, so the struct is allocated using kzalloc and we have a release function for it that frees the allocated memory, otherwise it is broken. ------------[ cut here ]------------ Device 'cros_ec' does not have a release() function, it is broken and must be fixed.

* | regulator: wm8994: Pass descriptor instead of GPIO numberLinus Walleij2018-11-151-9/+0
|/ | | | | | | | | | | | | | | | | | | | | Instead of passing a global GPIO number for the enable GPIO, pass a descriptor looked up from the device tree node or the board file decriptor table for the regulator. There is a single board file passing the GPIOs for LDO1 and LDO2 through platform data, so augment this to pass descriptors associated with the i2c device as well. The special GPIO enable DT property for the enable GPIO is nonstandard but this was accomodated in commit 6a537d48461deacc57c07ed86d9915e5aa4b3539 "gpio: of: Support regulator nonstandard GPIO properties".

The dependent clock, regulator and RTC drivers already can be built as a module. Building entire set of drivers as modules might require using initial ramdisk and can make booting process longer (due to probe deferrals). However adding such option is useful for testing and for multi-platform configurations. This also add required module authors to sec-irq.c file based on recent main contributors.
