[ Upstream commit dc39596a906d5b604f4e64597b6e904fc14625e8 ]
The devm conversion of kirkwood was incorrect; on removal, devm takes
effect after the "remove" function has returned. So, the effect of
the conversion was to change the order during remove from:
- snd_soc_unregister_component() (unpublishes interfaces)
- clk_disable_unprepare()
- cleanup resources
After the conversion, this became:
- clk_disable_unprepare() - while the device may still be active
- snd_soc_unregister_component()
- cleanup resources
Hence, it introduces a bug, where the internal clock for the device
may be shut down before the device itself has been shut down. It is
known that Marvell SoCs, including Dove, locks up if registers for a
peripheral that has its clocks disabled are accessed.
