[edk2-devel] [PATCH v2 2/5] MdeModulePkg/Core/Dxe: Fix MISSING_BREAK Coverity issue

[Ranbir Singh]

From: Ranbir Singh <Ranbir.Singh3 at Dell.com>

The function CoreIsSchedulable has switch-case code in which

       case EFI_DEP_BEFORE:
       case EFI_DEP_AFTER:

has a comment that

// For a well-formed Dependency Expression, the code should never get here.

It also has an ASSERT (FALSE); but this is applicable only in DEBUG
mode. Seemingly, for RELEASE mode, code should not be allowed to fall
through to case EFI_DEP_SOR: which is below the above two.

Hence, add return FALSE at the end.
