Subject: lib: devres: Simplify API devm_ioport_unmap() implementation
Date: Wed, 18 Sep 2024 22:48:14 +0800
From: Zijun Hu <quic_zijuhu@xxxxxxxxxxx>
Simplify devm_ioport_unmap() implementation by dedicated API
devres_release(), compared with current solution, namely
ioport_unmap() + devres_destroy(), devres_release() has below advantages:
- it is simpler if devm_ioport_unmap()'s parameter @addr was ever
returned by devm_ioport_map().
- it can avoid unnecessary ioport_unmap(@addr) if @addr was not
ever returned by devm_ioport_map().
