[edk2-devel] [PATCH] MinPlatformPkg/TestPointCheckLib: Add check for pointers
Posted by Zhang, Shenglei 4 years, 7 months ago 
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.
