[edk2-devel] [PATCH v4] MinPlatformPkg/TestPointCheckLib: Add check for pointers
Posted by Zhang, Shenglei 6 years, 4 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.

v2: Update copyright

v3: Fix the coding style.

v4: Update the logic in DxeCheckBootVariable.c.
    We directly return when BootOrder/Variable == NULL, in previous versions.
