302 *
303 * FUNCTION: AcpiNsRepairPackageList
304 *
305 * PARAMETERS: Data - Pointer to validation data structure
306 * ObjDescPtr - Pointer to the object to repair. The new
307 * package object is returned here,
308 * overwriting the old object.
309 *
310 * RETURN: Status, new object in *ObjDescPtr
311 *
312 * DESCRIPTION: Repair a common problem with objects that are defined to return
313 * a variable-length Package of Packages. If the variable-length
314 * is one, some BIOS code mistakenly simply declares a single
315 * Package instead of a Package with one sub-Package. This
316 * function attempts to repair this error by wrapping a Package
317 * object around the original Package, creating the correct
318 * Package with one sub-Package.
319 *
320 * Names that can be repaired in this manner include:
321 * _ALR, _CSD, _HPX, _MLS, _PRT, _PSS, _TRT, TSS
322 *
