[ Upstream commit c51592a95f360aabf2b8a5691c550e1749dc41eb ]
The sun8i thermal driver reads calibration data via the nvmem API at startup, updating the device configuration and not referencing the data again. Rather than explicitly freeing the nvmem data the driver relies on devm_ to release it, even though the data is never referenced again. The allocation is still tracked so it's not leaked but this is notable when looking at the code and is a little wasteful so let's instead explicitly free the nvmem after we're done with it.
This is a minor cleanup which as with so much of what's come in today's backports seems very questionable for stable.
