He's not, dev_get_regmap() just gets a pointer to an existing regmap -
no reference is taken and nothing is allocated. It's a helper that's
mainly there so that generic code can be written without needing the
regmap to be passed around. The caller is responsible for ensuring that
it will stick around for as long as it's used (generally by having it
lifetime managed with the device).
