6.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold johan@kernel.org
commit 9c75986a298f121ed2c6599b05e51d9a34e77068 upstream.
The mmio regmap allocated during probe is never freed.
Switch to using the device managed allocator so that the regmap is released on probe failures (e.g. probe deferral) and on driver unbind.
