[PATCH v2 0/3] {apply,alias}: convert pre-processor macros to enums

Revert changes to alias.c, and change variable types in apply.c

It is needed to revert changes to alias.c as the changed #define macros were actually returned values, so it is not right to change their types to enums.

Also, SPLIT_CMDLINE_BAD_ENDING is returned after changing to negative sign, breaking the validity of the conversion to enum.

The changes to apply.c are actually useful only if the variable types are enum, so change the type of variable int patch_method and function argument int side to enums as well.

Changes are in accordance to Eric's review of v1: https://lore.kernel.org/git/CADE8NappDSaZrMLeqak4is59oL=X1wJOj2eCLLjaCKyrnoK9PQ@mail.gmail.com/T/

Vinayak Dev (2):
  Revert added enum to #define
  Change types of int patch_method and int side to enum

Vinayak Dev (1):
  Change #define to enum in apply.c and alias.c
