I am OK with the patch. But the patch is using incorrect "Line ending":
python ./BaseTools/Scripts/PatchCheck.py -1
Checking git commit: HEAD
ShellPkg: add more items for smbiosview -t 3 .
The commit message format passed all checks.
Code format is not valid:
* Line ending ('\n') is not CRLF
   File: ShellPkg/Library/UefiShellDebug1CommandsLib/SmbiosView/PrintInfo.c
   Line:       if (Struct->Hdr->Length > 0x13) {
* Line ending ('\n') is not CRLF
   File: ShellPkg/Library/UefiShellDebug1CommandsLib/SmbiosView/PrintInfo.c
   Line:         PRINT_STRUCT_VALUE (Struct, Type3, ContainedElementCount);
* Line ending ('\n') is not CRLF

It is a good habit to use above check before send the patch. You should change your edit setting when you're working on edk2. Others are OK to me,

Do not send the patch again. I would make the change. Because of it is hard freeze now, the patch would be merged after the 202102 stable create.

By the way, are you follow the development process https://github.com/tianocore/tianocore.github.io/wiki/EDK-II-Development-Process to send the patch? I am confused why I cannot extract your patch thru extractor tool.

Thanks,
Zhichao
