The devm_kmemdup*() functions are defined in <linux/device/devres.h>, included from <linux/device.h> in 7.0. Did you consider adding them to <linux/device/devres.h>?

No, I haven't checked what Linux does for this.
I think factoring them out, I'd rather do in a dedicated commit not adding new stuff.
