Your whitespace doesn't quite match the edk2 coding style guidelines, but we can fix that during commit.

Subject: [PATCH] MinPlatformPkg/TestPointCheckLib: Add check for pointers

In DxeCheckBootVariable.c, add check for BootOrder and Variable that return EFI_NOT_FOUND when they are NULL.
In DxeCheckGcd.c, add check for GcdIoMap to ensure it not NULL when allocating memory to what it points to.
