That error causes driver to enable such control on all HP systems with the 92HD75 IDT codecs and results in unnecessary toggling of the GPIO on mute control manipulation. It also adds ...

Analyze and fix the following issue in the Linux kernel code: ACPI: support customizing ACPI control methods at runtime
Problem Details: Introduce a new debugfs I/F (/sys/kernel/debug/acpi/custom_method) for ACPI, which can be used to customize the ACPI control methods at runtime. We can use this to debug the AML code level bugs instead of overriding the whole DSDT table, without rebuilding/rebooting kernel any more. Detailed descript...
