Andy Shevchenko bc0b1a2036 ACPI: scan: Use unique number for instance_no ... [ Upstream commit eb50aaf960e3bedfef79063411ffd670da94b84b ] 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). Fixes: e49bd2dd5a ("ACPI: use PNPID:instance_no as bus_id of ACPI device") Fixes: ca9dc8d42b ("ACPI / scan: Fix acpi_bus_id_list bookkeeping") Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Cc: 4.10+ <stable@vger.kernel.org> # 4.10+ Signed-off-by: Rafael J.
