Re: [edk2-devel] [PATCH] RedfishPkg/RedfishPlatformConfigDxe: fix can not set one-of option issue.

["Igor Kulchytskyy via groups.io" <igork=ami.com@groups.io>]

Hi Nickle,
May I ask you a question. What is the point to allocate and copy buffer. Then delete the original buffer.
Could we just assign StatementValue->Buffer to TempBuffer and then assign NULL to StatementValue->Buffer?

TempBuffer = StatementValue->Buffer;
StatementValue->Buffer = NULL;

Result would be the same, but we do not need to allocate and free memory.
Or I do not understand something?
Thank you,
Igor

StatementValue->Buffer is converted from ASCII to Unicode by caller
already so we don't have to convert it again.
