H A D | internal.h | diff eb50aaf960e3bedfef79063411ffd670da94b84b Mon Mar 22 11:31:00 CDT 2021 Andy Shevchenko <andriy.shevchenko@linux.intel.com> ACPI: scan: Use unique number for instance_no
The decrementation of acpi_device_bus_id->instance_no in acpi_device_del() is incorrect, because it may cause a duplicate instance number to be allocated next time a device with the same acpi_device_bus_id is added.
Replace above mentioned approach by using IDA framework.
While at it, define the instance range to be [0, 4096).
