From 470508f63ad2483b1ae82ed67cd504ad408b2a35 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 6 Oct 2023 17:32:51 +0200 Subject: ACPI: bus: Add context argument to acpi_dev_install_notify_handler() Add void *context arrgument to the list of arguments of acpi_dev_install_notify_handler() and modify it to pass that argument as context to acpi_install_notify_handler() instead of its first argument which is problematic in general (for example, if platform drivers used it, they would rather get struct platform_device pointers or pointers to their private data from the context arguments of their notify handlers). Make all of the current callers of acpi_dev_install_notify_handler() take this change into account so as to avoid altering the general functionality.
