[PATCH RFC 3/4] thermal/drivers/acpi: Use hot and critical ops

From: Daniel Lezcano
Date: Wed Dec 09 2020 - 10:36:03 EST


The acpi driver wants to do a netlink notification in case of a hot or
critical trip point. Implement the corresponding ops to be used for
the thermal zone and use them instead of the notify ops.
