[PATCH] ALSA/hda: intel-sdw-acpi: Correct sdw_intel_acpi_scan() function parameter
Posted by Peter Ujfalusi 9 months ago
The acpi_handle should be just a handle and not a pointer in
sdw_intel_acpi_scan() parameter list.
It is called with 'acpi_handle handle' as parameter and it is passing it to
acpi_walk_namespace, which also expects acpi_handle and not  acpi_handle*
