[PATCH v4 34/35] acpi/bus: Remove redundant functions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



By this point all drivers switched from using .notify callback to
installing event handlers on their own. Remove redundant functions
acpi_device_install_notify_handler(),
acpi_device_remove_notify_handler() and acpi_notify_device().
