Subject: Update status based on DXGK and HKR enumearation
X-Git-Tag: upstream/v2022.01.04~21^2~1^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e8b332d24cf2daa906af84f3f01b3304c582e78c;p=platform%2Fupstream%2FOpenCL-ICD-Loader.git

Update status based on DXGK and HKR enumearation

khrIcdOsVendorsEnumerate currently does not consider
the status returned by DXGK and HKR enumeration
and returns TRUE only if HKLM regkey enumeration
results in successful adapterAdd.

Fix the returned status to consider successful
adapterAdd from DXGK and HKR enumeration.

Also, set freed adapger pointers to NULL to avoid
potential double-free issue.
